[vbox-dev] Performance of 2.6.20 with openvz patches In VirtualBox, any advice

[SErgey Ya. KOrshunoff]

Hi! There is a 25% performance lost in a nbech test  for 2.6.20 kernel
(inside VirtualBox) with openvz patch
http://git.openvz.org/?p=linux-2.6.20-openvz;a=commitdiff;h=c4eff5898dee116fc410cc543cae074c21c818ba
Patch is small. But it is unclear what to do to trace a performance lost
and now to resolve it.

Any advice?

PS: pi calculation in VirtualBox is 25% slower than on real hardware (

With above patch for openvz a pi calculation inside VirtualBox go to be 50%
slower than on a real hardware. Sad case enougth
