Hi all, in the thread about RENDER extension, it has beem mentionned that XFree was performing much slower (ie 2 or 3 times slower) than imlib2 (sorry I don't really remember in which tasks). The reason seemed to boil down to the fact that imlib2 has arch specific asm instructions (I think mostly for x586 via MMX or SSE or whatever) for certain crucial functions. My question is why not do that also in XFree (borrowing/adapting codes from images manipulation libs)? By choosing carefully the functions to optimize (that would mean only a few small function so that the maintainance is as easy as possible) we should avoid too much mess, keeping portability by using the "old" functions for arches with no specific optimizations. Does that sound reasonnable? Bye Manu
