Re: [Xen-devel] Credit scheduler
How many physical CPUs do you have, and what is the IO workload that one of the VMs is running?

Hi
I have noticed that VMs are typically spending 3 microsecs or less before they are being prempted. I thought that the credit schduler time slice was 30 ms. I have 4 VMs running and they are all cpu intensive except for 1 (which is IO intensive) but having a VM spend max 3 micro secs before being kicked out seems strange.
Is there something else going on that i am not aware of. Is the time slice really 30 millisecs? I am using default parameters of the credit scheduler.
Thanks
