Actually what I'm interested in is stability. I had a 2% measurable clock wall improvement just for fpu overhaul (bandwidth increased 146 MB/s to 149 MB/s on my P3, 450 MHz). The main effort will be on P4,Xeon and on amd64 porting for Athlon (I'm speaking about performancy matters). But now I need some very intensive testings about "base-code".
