Hi, > You should also try out "atop" instead of just using top. The major > advantage is that it gives you more information about the disk and > network utilization. Thanks for the tip, I tried it and if the red lines are any indication, it seems that atop thinks my disks (md raid 1) are the problem being busy over 60~70% of the time. However that is sort of expected since most of the expected activity on the server is smtp/pop3. Unfortunately, I did not know about atop previously and don't have a baseline to compare against :( _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
