I was running a frame loss test the other day against an rhel4 smp kernel and a non-smp kernel. I noticed I was getting better numbers when I ran the non-smp kernel. I was surprised by that. Anyone have any insight into this? I am running this with e1000 dirvers. I also ran a test where I ran the smp kernel with hyper threading turned on and off. There, the frame loss numbers were worse when hyper threading was turned off. I would not have thought that having hyperthreading turned off would make such a big difference. Just trying to make sense of these numbers :-) --joubert
