Hi, > Also try setting kern.threads.virtual_cpu=1 if you have > more than 1 cpu (this will limit it to 1 KSE). Our boxes have 2 CPUs and HTT is activated. Interesting. With kern.threads.virtual_cpu=1 it works also in the libpthread case, but while there are still some fork() calls it works better. With kern.threads.virtual_cpu=2 it's slower. And With kern.threads.virtual_cpu=4 its really slow. If I run clamd in foreground mode everything works as it should. More interesting, the CPU load drops significantly (500-1000%) ! Something is seriosly broken here. Martin
