I've made some tests with "john --test" and "transcode", wich are both multithreaded apps. For example if I launch transcode it takes between 50% and 55% cpu (on top), and if I launch a second transcode session on another file, the total cpu used on top is 100%, without lower the speed of the first transcode session. The same behavior occurs with john. A single "john --test" give me some speed results, and the same command with a transcode or second "john --test" give me the same speed results but now with 100% cpu used. I made a "portupgrade -auf" just after building and installing my SMP kernel and World, to be sure all is up-to-date. So it's seems it's not a "top" output problem, but a real underuse of the computing power. %uname -a FreeBSD wks02.chez.oim 6.1-STABLE FreeBSD 6.1-STABLE #0: Thu Aug 17 18:47:31 CEST 2006 laurent@wks02.chez.oim:/usr/obj/usr/src/sys/WKS02_SMP amd64 Does anyone could explain me what's happening with my system ? -- Laurent C.
