服务器上什么程序都没开,结果System 这个进程老是占CPU的30~40
于是发邮件问机房是不是网卡驱动或者什么的问题!结果机房回复
We have tested your server and it seems to be fine, the CPU usage is consistant around 40-50 irrespective of network speed. We did a download from Fremont1 data centre and the CPU usage was around 40-50 and then we did a download from Fremont1 and two San Jose data centres and the CPU usage was still around 40-50.
So the increase in bandwidth allocation (or) the network usage doesnt seem to create an impact on the server. Please see attached screenshots taken during the tests.
