please correct the Bugreport 40454 with the values of gcc 4.1.2 4.2.5.
it seem 4.1.2 reach near same speed as 3.4.0 but all later gcc are slower in some programs. this can also see on ffmpeg. also on X86 ffmpeg see here it is see. what is change after 4.1.2 that can cause slower executable speed ? here can also see on ffmpeg X86 that GCC compiler upto 4.1.2 get near same speed, then on 4.2.4 it get suddenly slower. http://multimedia.cx/eggs/intel-beats-up-gcc/ On 16.08.09, you wrote: > Hi, > > I found out that GCC 4.4.x build of minigzip from zlib package is a lot > slower compared to GCC 3.4.0 build.
