Hi, did you try to use pmcstat to determine what is the heaviest task for your system? # kldload hwpmc # pmcstat -S inst_retired.any -Tw1 Then capture several first lines from the output and quit using 'q'. Do you use some firewall? Also, can you show the snapshot from the `top -HPSIzts1` output. -- WBR, Andrey V. Elsukov
