Hello George,

How did you measure Cache/ TLB misses etc while using/profiling this new scheduler ? Any tool that you`ve used which works with Xen ?

Thanks,

This patch series introduces the credit2 scheduler. The first two patches
introduce changes necessary to allow the credit2 shared runqueue functionality
to work properly; the last two implement the functionality itself.

The scheduler is still in the experimental phase. There's lots of opportunity to contribute with independent lines of development; email
