Como usuario regular de Sumatra PDF, y dado que los últimos cambios del código, permiten una compilación directa x64, me ha extrañado que no haya nadie haciendo compilaciones regulares para esa plataforma.
Por tanto, he tenido que tomar la iniciativa, y desde hoy iré publicando con regularidad (al menos una vez al mes), compilaciones actualizadas para Windows de 64 bits de Sumatra PDF, en el proyecto que he llamado SumatraPDF x86/x64 Optimized Builds (SumatraPDFOpt).
Sumatra PDF Opt, parte de los últimos fuentes en el repositorio de desarrollo, donde no he realizado ningún cambio en absoluto.
Si hay novedades en cambio en la tool chain, nuevas opciones de compilación, un nuevo compilador, y un compresor diferente, hacen que mis binarios sean más pequeños, veloces y compactos.
Podéis descargarlo, y consultar más detalles en nikkhokkho.sourceforge.net/static.php?page=SumatraPDFOpt
Could you make PGO builds for SSE2?
Since now anonymous, all my builds have PGO enabled. It is more time-consuming, and seems that Visual C++ 2010 does not like so mucho the PGO SSE2 builds, they are now ready at SumatraPDFOpt builds.

Thank you

Pity. Hope it is not too much over time and you will be able to continue to provide them in the future. It seems that for x86 it is only 10kb smaller, and I wonder how to test the speed up. Any suggestion?
Hi anonymous, I will try to do my best in continue providing PGO optimized builds for all targets in the future.
If interested in bechmarks, you can see the results I obtained at http://code.google.com/p/sumatrapdf/iss … d=1129#c16
For doing your own tests, you can use the -bench switch like:
"c:\Program Files (x86)\utilidades\SumatraPDF.exe" -bench "c:\file.pdf"
This will render internally the whole PDF, so it is easy to keep track of the time spend with an stop-watch or similar tool.
The size reduction is before compresing the executable, and comparing it with the builds without PGO, anyway, I encourage you doing your own tests comparing them with the official SumatraPDF and keep us informed on the results.
Regards.
Hi Guti)), than you for the bench switch, it does not seem to be documented on the official page. So I went on and run some quick tests.

Summary:
SSE2+PGO seem to provide a nice 15% speedup on the test file and up to 22% on the profile file.
Updated MuPDF merged in version 2817 has the same speed as the previous one.
Final compressed SSE2+PGO file is 35KB (2%) larger than official build.
Next: need a tool to that also shows memory usage or, better, it could be shown with the -bench switch as output. Ideally, it could also integrate the timer.exe code, which is public domain, to be self-sufficient and may be even automate speed tests.
Thank you very much for your detailed benchmarks anonymous, and glad to see this 15% speed improvement.
As for the size, consider that my builds use ASMLib that require an overhead of about 15 KB, for a benefict of a 0.5% overall speed increase, and have some SyncText features enabled. Those features, are not available in the official prerelease, so extra code is required.
Also, since my builds favor fast code due to enhanced compilation switches, they are probably generating slightly larger code. More if we consider that SSE/SSE2 and x64 instruction sets, has bigger sizes.
Will try to increase this figures in the future. Do not hesitate suggesting any ideas you could have to build even faster compiles.
I have been looking for that memory tool but did not find any. Anyway, expect a slight memory usage increase in my builds due to the reasons mentioned.
Using ProcessExplorer, they are in the range of 1%-2%.

Oh, dont worry, I was just reporting it for the sake of completeness.
> Do not hesitate suggesting any ideas you could have to build even faster compiles.
Well Im not quite versed in software optimization and compilers to do so. But I can do some testing I you want. I saw that in the issue db you posted a comparison with different compiler settings. If you are interested and provide the executables, I can do the same testing on my computer.
It may be a stupid idea, but can a universal x86 executable be compiled? The one that will automatically use SSE/SSE2 if the CPU support them?
> I have been looking for that memory tool but did not find any. Anyway, expect a slight memory usage increase in my builds due to the reasons mentioned.

Yes, the usual space vs. time trade-off. I dont mind that, but it would be interesting to measure it quantitatively.
I have created an updated SSE2 version using latest r2833 source, with some additional tweaks. Find it at guti.isgreat.org/images/SumatraPDFOptx86SSE2.zip and let me know if speed increase is noticeable on your side.
If everything goes fine, this will be added to the my official SumatraPDFOpt SSE2 builds.
I get "La página a la que intentas acceder, no se encuentra disponible en este momento." when using the link above. Wrong address or access rights?
It seems that the new server is preventing hot-linking, so I have updated the official downloads links, with the updated SSE2 version for you.
Get it on http://guti.isgreat.org/static.php?page=SumatraPDFOpt in the download section.
Run the benchmarks, but was quite busy so could not upload them earlier. Two CPU tested this time: Intel Core Duo L2400@1.66GHz and P4@2,66GHz.

For some reason measurements are unstable and tend to get worth with each subsequent test, but SSE2+PGO builds are still ahead. Could have been the Intel SpeesStep, but after checking the processor does not support it. Will try to investigate further with the next version. 🙂
That are magnific and consistent results.
For your information there is an update available at the level of r2958. But the good news is that after that and upto the current source at level of r2998 the SumatraPDF team has made some more optimizations.
Additionally, I plan to upgrade to Visual Studio 2010 SP1, that should hopefully give a slight improvement.
Yes, I already downloaded your build r2958, but in the light of what you are saying I will wait for your next build before re-running the tests.
It will be interesting see if the SP1 is any faster, even though I haven’t seen anything about speed optimisations, except for upcoming processors: http://support.microsoft.com/kb/983509
On another register, do you have access to the Intel compiler? It is rumoured to produce the fastest code and with the code cripple for AMD CPUs finally removed it can be worth trying.
> the good news is that after that and upto the current source at level of r2998 the SumatraPDF team has made some more optimizations.
Are you sure about this one? I just downloaded version 1.4 that came out, and it time the same as rerelease-2831 and sometimes even slower 34 vs 32 and 31 vs 29 on the two test files. Or perhaps the 1.4 branch was created before the r2998?
Even if not yet officially announced (I will be doing some tests these days), the download page of SumatraPDFOpt contains builds r3002 now, made with Visual C++ 2010 SP1. They seem to be a bit faster on x64, but the same on the rest.
I am aware of Intel C++, and in fact tried to build SumatraPDF with it some weeks ago. The problem is that SumatraPDF relies on makefiles, and it was not transparent nor trivial to figure out how to build, so no success on that. Maybe will try again later.
I see those optimizations in smaller executables, by cleaning-up lots of unused code, but have not done performance tests, so maybe you are right, and they are the same speed. Or maybe the rewrite on C++ of some packages, have made it a bit slower. Will need further investigation on that.
> the download page of SumatraPDFOpt contains builds r3002 now, made with Visual C++ 2010 SP1.
I tried to download a close version of regular Sumatra, but it seems that anything before 3013 does not exist. 🙁 I can’t even understand, from reading the http://code.google.com/p/sumatrapdf/updates/list, what revision would the release 1.4 correspond to. So what version should I compare it to?
> I am aware of Intel C++, and in fact tried to build SumatraPDF with it some weeks ago. The problem is that SumatraPDF relies on makefiles, and it was not transparent nor trivial to figure out how to build, so no success on that. Maybe will try again later.
Good luck then, and keep us informed.

Indeed, version 2958 is smaller by 15kB, compared to 2833.
> but have not done performance tests, so maybe you are right, and they are the same speed. Or maybe the rewrite on C++ of some packages, have made it a bit slower. Will need further investigation on that.
Ready and willing! Just post the executables 🙂
Hello again Guti.
Have you seen these threads on the main SumatraPDF forum? http://forums.fofou.org/sumatrapdf/topic?id=1924321 http://forums.fofou.org/sumatrapdf/topic?id=1853323
The author report some interesting size improvement and VS2010 support (also I guess you already have the latter one 🙂 )
I have updated the builds to the level of 1.5 r3116.
As usual, find them at http://guti.isgreat.org/static.php?page=SumatraPDFOpt and do not hesitate reporting any issues or performance metrics.
Thank you.
Since there was a corresponding pre-release version 3116, I did some more extended testing and added x86 generic executable. Also tried the SSE build, but it turned out to be binary identical to the SSE2. Does it mean that there are no possible SSE2 optimizations in the code? Or are the executables actually “universal” and contain both types of optimizations? Unfortunately, I don’t have an SSE-only computer to try it out.

A ~15% speed-up for the PGO file and 8-10% on the test file. The speed fluctuations observed last time are mostly gone, but their origin is still unknown.
Overall, the speedup due to optimizations is real and consistent across versions. The test file speedup is ~2/3 of the profile file.
Plain x86 and SSE2 optimizations produce almost identical results, and SSE and SSE2 executables are identical at the binary level.
Now that the test chain is in place, it would be interesting to test the WDK build from this thread: http://forums.fofou.org/sumatrapdf/topic?id=1924321, but the executable file at the bottom of the thread is gone. Do you think you can compile a new one using the patches from the thread?
BTW, SSE2 were first introduced in Pentium4, you may want to add this on your download page.
About the 3 x86 builds there are some clarifications that probably will help you:
– libjpeg-turbo uses CPU runtime detection, this means that even if you use the regular x86 build, when decoding JPEG images, it will use MMX, SSE or SSE2 if available.
– Rest of the code is statically optimized, this means that x86 version, will not use SSE nor SSE2 even if available for instance while rendering to screen, or while decoding the PDF itself.
– SSE2 binaries are identically to SSE due to a bug in Visual C++ 2010 that when combined with PGO makes it crash. It was reported to Microsoft at http://connect.microsoft.com/VisualStudio/feedback/details/643255/sse2-produces-internal-error-ha-occurred-in-compiler but they were unable to reproduce it. So probably it is a strange combination of the samples in PGO combined with some source code combinations. It did not happen with SumatraPDF r28xx for instance, and has not been solved with visual C++ 2010 SP1. In that case, until solved SSE2 are equal to SSE, since only SSE1 instruction set is used.
Problem with WDK is that it requires building with Visual C++ 2005, which does not support PGO, and probably generates slightly slower code.
Of course, it allows to dynamic link against Visual C++ runtimes dynamically (msvcrt.dll), so this code is not embeded on the executable, which could save in a best case scenario upto 260 Kb. of uncompressed code in the x86 builds, and 354 Kb. in the x64 builds.
The only drawback as you have probably read, is that the DLL file needs to be installed on the system, but it comes out-of-the-box in all recent versions of Windows.
In a few words, WDK builds are smaller, but will not be faster at all.
Hello Guti).
Thank you very much for this detailed explanation. A very instructive reading.

This may explain the very small difference between the normal x86 and SSE builds. But does it mean that most of the speedup comes from image decoding or from PGO? If you can provide corresponding builds I can test it for you.

And since the original reporter did not provide more information it is not likely to be fixed, unfortunately. 🙁

Are you sure? From what I understood from reading the posts, the first patch adds support for VC2010: “patch if you want to give it a go for msvc2010
http://pastebin.com/PzaLEd4V”
> The only drawback as you have probably read, is that the DLL file needs to be installed on the system, but it comes out-of-the-box in all recent versions of Windows.
Correct me if I am wrong. Current SumatraPDF, be it official or yours, are statically linked and does not require any external library, while the WDK build will require the msvcrt.dll v6.x, but was basically included with every Windows version since 98SE?
> In a few words, WDK builds are smaller, but will not be faster at all.
I’d be interested to give it a try anyway. 😉
Could you also build x64 version of PdfFilter.dll? This filter is missing for the x64 version of Windows and MS Desktop Search.
By the way, what is the use of libmupdf.dll in the SumatraPDF folder? Does it require to be built as x64 to use with your optimized SumatraPDF.exe?
Hi Cecil,
I already answered you by email, nevertheless, here is my reply.
libmupdf.dll is the muPDF library, which can be used if you dynamically link SumatraPDF. It makes the EXE smaller at the cost of requiring to use the DLL, and the loading speed is a bit worse.
As for the IFilter, I tryied to build it some time ago, but gave some compilation problems under x64. Will try again when I have some time to hack the makefiles.
Thank you very much, I am glad you liked the extra performance of my builds.
Regards.
There is something wrong with your link

OTOH, this one works ok:

Hello doknir,
For some reason my free ISP modified its location to http://guti.is-great.org
BTW, can you repair links inside the following pages:

https://www.javiergutierrezchamorro.com/compilaciones-optimizadas-de-sumatra-pdf/1479
Thank you for the point doknir. I have fixed them.
