[Bug 1100843] Re: Live Migration Causes Performance Issues

Tue Apr 16 17:07:54 UTC 2013

The results of comment 23 suggest that the issue is not 100%
reproducible.  Can you please run the benchmark 3-4 times
(presave/postrestore) and showall 4 results? One benchmark only, e.g.
"simple read" will do.

Also please try putting a big file on disk (something like "dd
if=/dev/zero of=bigfile count=64K bs=64K") and then doing "cat bigfile >
/dev/null" after restoring. Please check if that makes performance more
consistent.
