If it's the VMware document I'm thinking of (titled "Timekeeping in
VMware Virtual Machines"), then the issue is that emulating the timer 
interrupt can cause a heavy load on the host if the guest timer is 
configured to run at a high rate.

At the BIOS standard rate of 18.2Hz, no modern machine is even going to 
notice.
