Hello,

the main question is:
what system OpenVZ is compared with?
Have you got a chance to measure performance on original CentOS 5.2 with original 2.6.18-92.1.1.el5. redhat based kernel?
It would be great if you have any numbers/charts/tables etc.

Do other VEs are almost idle when MySQL VE (105) handles requests?
If it's lack of CPU you can play a little with CPUUNITS/CPULIMIT values.

You can also try to play with --ioprio parameter
( http://wiki.openvz.org/I/O_priorities_for_VE ) or change i/o scheduler ( /sys/block/sda/queue/scheduler [ try deadline one] ).
