Tue Jan 3 14:06:20 2017  aweisberg:iksaif: That's from Benedict I think. Basically don't park again if the amount of time remaining is 1/16th of the time we are going to park for.
Tue Jan 3 14:06:29 2017  aweisberg:And you have just proved that deserves to be commented.
Tue Jan 3 14:28:45 2017  iksaif:yep, I ended finding out why
Tue Jan 3 14:28:59 2017  iksaif:and I sent a patch to fix what I thing is a bug + adding a comment here

Tue Jan 3 15:21:53 2017  aweisberg:iksaif: Great, which ticket?
Tue Jan 3 15:31:06 2017  aweisberg:Uh, in Apache JIRA all my filters are gone?
Tue Jan 3 15:31:36 2017  aweisberg:Ah, half logged in. Shows as logged in but isn't.
Tue Jan 3 15:31:47 2017  iksaif:https://issues.apache.org/jira/browse/CASSANDRA-13090
Tue Jan 3 15:32:47 2017  iksaif:my starting point was "I'm doing too many ctx switch", I increased the window size and the OTC backlog became huge.
Tue Jan 3 15:33:23 2017  iksaif:note that coalesing may not be better only because it reduces the number of packets, but also because LinkedBlockingList is super inefficient when empty

Tue Jan 3 17:04:00 2017  iksaif:aweisberg: you're right, some things have disapeared why they should not have. I'll make sure I'll do that with the exact same data directory (backing it up and restoring it after)
Tue Jan 3 17:04:05 2017  iksaif:+ your timing patch
Tue Jan 3 17:04:48 2017  iksaif:(but I'm confident the effect is positive, restarting cassandra on this machine just take ages without the patch)
