Your mysql db is only using 496Mb of ram? i have a server with 1GB ram
where mysql uses more mem than yours does - you should probably tune
your server system variables a bit to utilize your memory better.

you're still in 32-bit mode the extra memory over 4Gb can actually slow the
system down since it has to page between memory zones.
It was choosen to run on i386 i.e. 32-bit mode for compatibility to Java
and other servers in the farm.
But as you can see not even the 3GB border is touched:

But despite the 99% CPU, vmstat thinks the system is idle.
