The system is an X serie Sun server with 8 cores, 8GB RAM.
I had it running with a single cpu for some months, then I wanted to switch to 4 cpus + ioapic.
To do this, after enabling the switches on the guest, I had to start again from win CD and run a recovery, to have windows install the mp kernel.
Then I reinstalled service packs.
Everything went fine, I got my cpus visibile.
But, I did not find any improvement, the machine is sometimes very slow compared to a native system with similar hardware.
Can someone suggest specific switches to make the guest faster?
Thanks for any help,
Gabriele
