| |
This is the more work base on my v1 patchset which is posted some months ago, it can be found at: https://lkml.org/lkml/2011/2/22/68
Change log: - sort memslots base on its size and do the line search instead of binary search base on gfn, it is from Avi's idea. - in order to reduce cache footprint, memslots are sorted in the array of kvm->memslots->memslots[] and introduce a table to map slot id to index in the array
There is the performance result:
autotest for RHEL.6.1 setup/boot/reboot/shutdown(average): ept=1: before: 449.5 after: 447.8 ept=0: before: 532.7 after: 529.8
kernbench(average): ept=1: before: 127.94 after: 126.98 ept=0: before: 196.85 after: 189.66
