Hi folks,
Could you enlighten me how to achieve proportional IO sharing by using cgroup,
instead of qemu's io-throttling?
My qemu config is like: -drive
file=$DISKFILe,if=none,format=qcow2,cache=none,aio=native
buffer_find_nonzero_offset() is a hot function during live migration.
Now it use SSE2 instructions for optimization. For platform supports
AVX2 instructions, use the AVX2 instructions for optimization can help
to improve the performance about 30% comparing to SSE2.
Zero page check can be faster wit
