Hi,
Do you have some performance numbers to show this helps? Were those
taken on a normal system or were they taken with one of the compression
accelerators (which I think the compression migration was designed for)?
Yes, i have tested it on my desktop, i7-4790 + 16G, by locally live migrate
the VM which has 8 vCPUs + 6G memory and the max-bandwidth is limited to 350.
During the migration, a workload which has 8 threads repeatedly written total
6G memory in the VM. Before this patchset, its bandwidth is ~25 mbps, after
applying, the bandwidth is ~50 mbps.
BTW, Compression will use almost all valid bandwidth after all of our work
which i will post it out part by part.
