    Maya, 3dsmax, photoshop 32-bit all do use multithread quite nicely. You are probably not using filters, plugin's, etc, that really don't need multi-thread. Even look at some thing like CoreAVC which is a h264 decoder that is most definiately threaded. There are literally hundreds of multithreaded apps out there in 32-bit form. Another excellent example is handbrake.

    As far as the "switched to 64 bit so they don't update 32" well that is a bunch of bubkus, since 32-bit and 64-bit have NO bearing if a app is multithreaded or not. I have been happily enjoying the experiences of multithreaded apps since I first got a dual cpu celeron system over a decade ago and at that time there was only 32-bit windows.

      So far none of the applications you've suggested or at denniskarlson.com have used 4 processors simultaneously.

      Though I do know that Apache compiles with more than 2 processor cores on a 64 bit Linux platform. 32 bit results to follow presently.

        Found ONE so far.

        Apache 2.2.11 32 bit that is installed by Phoronix-Test-Suite actually uses 4 cores simultaneously.

        So I stand corrected on that point.


        There are VERY FEW applications that multi thread correctly, whether 32 bit or 64 bit.

          Did you ever go back and update any of your 16 bit code once Windows 95 released? I sure didn't. AND I'm not updating any of my 32 bit code any more either. Your mileage may vary. Heck I had to dig to find a CD that has a 32 bit of an OS on it today. I run 64 bit OSs exclusively at this point, except when testing things like this.

            And the final point I have to make on this thread.

            Here's the link to the results of 32bit vs 64bit build-apache using Phoronix Test Suite.

              Sorry but those apps were multithreaded waaaaaaaaaaaaay before 64-bit versions of the OS or APPS were even created. So your impying that they REMOVED smp code?

                LMFAO again, ok so you are comparing a system with pentium pro optimizations (nothing more, no SSE, no nada) vs a kernel (32 or 64-bit ) which has special instruction set instructions? Give your head a shake.

                  See (BTW totally ass drunk but still sober enough to prove you WRONG),

                  PS don't make me install 32-bit again, luckly I had the 32-bit version already built up in openSUSE's local build service with the same flags.

                    Same system, same OS, same flags. BOOOYA!

                    PS. any gentoo Stage 1 or LFS user could have shown the same results.

                      From wine's results in this one and on many others is obvious that if you compile the same program with the same compiler under both OSes, then Linux will be faster in almost every case and by a large gap.
