※ 引述《supermico (上帝愛你)》之銘言:
: 剛裝1台FreeBSD 8.0 , 4核心 HTT的新主機(i7 930) ,
: 用dmesg |less看8顆cpu.(cpu0~cpu7)
: 但打top -IS , 卻只能看到2個cpu ?
: PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
: 11 root 8 171 ki31 0K 64K RUN 0 559:54 800.00% idle
: 12 root 24 -32 - 0K 192K WAIT 1 0:22 0.29% intr
: ps.以前的q6600打top -IS可以看到4個cpu狀態 , 如下 :
: PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
: 11 root 1 171 ki31 0K 8K CPU3 3 19.5H 100.00% idle: cpu3
: 12 root 1 171 ki31 0K 8K CPU2 2 19.4H 100.00% idle: cpu2
: 14 root 1 171 ki31 0K 8K RUN 0 19.4H 100.00% idle: cpu0
: 13 root 1 171 ki31 0K 8K CPU1 1 19.4H 98.68% idle: cpu1
: 16 root 1 -32 - 0K 8K WAIT 1 6:23 0.20% swi4: clock sio
top -P 最上面就會顯示所有 cpu usage 啦 ...
7.1R 之後的 top 都有這選項
