I asked about xfree because I know the kernel shouldn't improve the speed much.
I'll try -O3 even if I think that the O4 switch, not reported as error at compile time, already optimize the code well.
Unfortunately, I cannot oveclock the system: read the specs below.
So, are there around xfree srpms I could use? If not, is following the instructions provided in the xfree site trouble free (with mandrake, I mean)?
Maybe there is another choice... linux didn't recognize my vodoo banshee pci well: mplayer cannot use it even if I enabled the appropriate options at the compile time. It seems that the 3dfx (or similar, I don't remember) device is not present.
If someone tells me (in addition to the previous question) how to be sure to have the video card recognized, I can try to use that as vodeo output (I use xv now, I tried everything but it's the fastest with my system).
Thank you very much
Olaf

Don't know how hard it will be, but why don't you try to recompile divx player/driver yourself? Probably you will get better improvement with this than playing with kernel if you are not short of memory or running many services at the same time. I have never played with Xfree, but it seems to me that you could get more improvement than playing with kernel in this precise case. If you want to have a look on recompiling divx stuff, you'll probably find in source files an archive called something like 'Makefile' in wich you can change the optimization levels for gcc. Most programs (including kernel) are optimized in level 2 (-O2) and compatible with any 386 or (as in Mandrake) compatible with classic Pentium. Maybe you can change this to your specific processor and change some optimizations: -O3 --> Mainly will tell gcc that it can re-order machine level instructions to minimize queues of instructions waiting to be procesed -march=athlon --> Object code will be athlon processor specific. Depending on your processor it will be i686, i586, pentium, ... See 'man gcc' for more information are there are more options, but they will probably give you less improvement.I have had up to 12% improvement on a program I did myself just by using -O3 and processor specific. Another thing is trying to overclock a bit the graphic card and/or main board/processor. Good luck!!! (and tell us about!!! ;-))
