Hi,
Actually I want to port my pthread performer application from SGI box to
linux , but when I didn't get the framerate that I expected, I found out that
linking performer app with pthread library make the the framerate slower, even
if I don't use pthread function at all. I tried it with the original perfly
source code, without link it with pthread I get 25 ms draw process for
the file sj_texgen.pfb, and when I put -lpthread during linking, I get
40 ms for draw process (I think 60% speed decrease is too much for nothing).
I use redhat 6.1(kernel 2.2.12,glibc 2.1.2),XFree 4.0.1,nvidia driver 0.94,
last performer version, ASUS geforce 2,athlon thunderbird 750 mhz,128 mb ram.
So, I wannt to know if someone else has the same problem, or it is only my
problem.
And another question that maybe doesn't belong to this mailing list, I tried
perfly with tux.pfb, it works fine, but if I use wireframe mode , the framerate
dropped from 60+ frame/second to 1 or 2 frame/second, although this model
is very simple model (it is not only for this model, I use the same pc spec
like above, and I am sure that I removed the mesa opengl library).
thanks for the help,
cahya.
