Thread-topic:	Scheduler questions

Hi all,

1. vcpu_kick - Is it immediately perform a context switch or just push the vcpu that was specified to be the next in line? is there an overhead time? how much time pass between executing vcpu_kick until the vcpu is actually running?

2. If I want the scheduler to be a bit more interactive, can I decrease the default msecs per slice (CSCHED_MSECS_PER_TSLICE)? What will be the side effects of that?

Thanks in advance,

Guy.
