some nice stats,
showing that the CPU usage is primarily in the Apache daemons.
Yes, and the vmstat showed that the CPU is even idle while disk
I/O is rather high. It's not mysql doing nothing. It's mysql
waiting for the disk. The new server, how many disks will it
have?
Breakthrough! Improving disk throughput for the database would probably do
wonders for Wikipedia performance.
Is it possible for you, hardware wise, to leave Apache and PHP on the
current server and move the database to a system with a higher performance
controller and multiple disks? If the database is will continue on the
current server, a controller upgrade may be in order.
