Michal Linhard <mlinhard at redhat.com> made a comment on [bug 886549|https://bugzilla.redhat.com/show_bug.cgi?id=886549]

In other tests there is a little unevenness

by eye it's around 8%, and it's only during the crash. I need an opinion whether this is tolerable. Both tests use numSegments=10*clusterSize.

I'm going to count the exact numbers for both throughput and entry distribution (that's taken from stats).
