That seems very wrong. What depth is your display set to?
SDL_BlitSurface() shouldn't take 50 ms for even a 1024x768 blit, since
it's using inline assembly version of memcpy(), unless it's doing a
complicated unoptimized conversion blit (which almost never happens)
What is the output of the testvidinfo program in the test subdirectory?
What's the output of cat /proc/cpuinfo?
