[Bug 482486] Re: Ubuntu 9.10 and Vbox 3.0.8-3.0.10 lag issue in XP vm.

[Perryg]

I have tried the kernel release v2.6.32-020632-generic from the Ubuntu Kernel PPA and it does seem to help a lot without compiling yourself see link http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32/ 
According to the change log they did some work with the CPU time and other related areas that improved the speed.

I did re-compile the 2.6.31-16-generic x86_64 with the host timer freq
set at 250Hz and while it did work better it did not work as well as the
latest release from the PPA.

The sound is still garbled with 2.6.32 and this may be due to the fact
that the KTF is still set to 100Hz but I have not gotten that far into
the new kernel yet.

@sjalloq I found this an easier build instruction and it does work.

Also it is important that you remember that you will need to recompile
VBox for the new kernel so you will need both the linux-headers all and
the one that is specific to your build.  If you have special video
drivers they will need to be recompiled as well.
