Good to get confirmation; thanks. :-} > however the interesting thing is that while it took more wall-clock time, > it took less system and user time. Aye; Dan Nelson also pointed that out, and it is rather interesting. > you might try the 4bsd scheduler to see what that does.. OK -- but we were using the default scheduler in each case. The basic point I'm making here is the apparent performance regression for similarly-configured systems under 7.1 vs. 8.1. > also, compare the configs of the two kernels Well, under 7.1, we used the MAC kernel config; since that didn't exist for 8.x, I used GENERIC for it. (We had used GENERIC under 7.1 until a certain application we use required MAC support. I haven't tried to make that application work under 8.x yet, as there are plans to deprecate its use.)
