Hi Daniel,

Thanks a lot for testing!
Is the head of lruv19 branch 9ee69337d51d on my github? We may just hit a narrow
window, which I just removed the old lruv19, and updated a new one. But even the
old version has same performance behavior too. :)

Yes, the lru lock replace has no clear performance changes, unless the 
migration/compaction compete on different lru locks which require to run in
different memcgs, and then tphscale should get some benefit.

Hi Daniel,

Thanks a lot for testing!
Is the head of lruv19 branch 9ee69337d51d on my github? We may just hit a narrow
window, which I just removed the old lruv19, and updated a new one. But even the
old version has same performance behavior too. :)

Yes, the lru lock replace has no clear performance changes, unless the 
migration/compaction compete on different lru locks which require to run in
different memcgs, and then tphscale should get some benefit.
