Another reason to reduce the frequency is for servers with many virtual machines running since each one needs to service the interrupt and a machine with a thousand virtual machines running has to service ((1000 + 1) * Hz) timer interrupts. That is excessive when most of the virtual machines might be idle.

Certainly such a setup would be hand-tuned hopefully...
