Fri Sep 16 15:22:43 2016  ostefano:For some reasons C* 3.0.9 shows way lower latencies, which is awesome but I can't track it down to a specific solved issue. Thought it was worth sharing this data point.
Fri Sep 16 15:30:02 2016  thobbs:ostefano: interesting, lower median? Lower 99th?
Fri Sep 16 15:31:52 2016  jeffj:ostefano: 3.0.0 -> 3.0.9? or coming from earlier version?
Fri Sep 16 15:32:10 2016  ostefano:99th 999th
Fri Sep 16 15:32:22 2016  ostefano:reading
Fri Sep 16 15:33:02 2016  ostefano:I'd say even 9th
Fri Sep 16 15:33:07 2016  ostefano:*95th
Fri Sep 16 15:33:16 2016  ostefano:3.0.8
Fri Sep 16 15:34:59 2016  ostefano:https://snag.gy/soaphf.jpg
Fri Sep 16 15:39:42 2016  ostefano:yeah, maybe "way lower" was a tad exaggerated, but I can definitely see the trend
Fri Sep 16 15:41:38 2016  thobbs:ostefano: could just be a side effect of restarting, fwiw
Fri Sep 16 15:41:56 2016  thobbs:I would wait a couple of days and see if the trend continues
Fri Sep 16 15:42:36 2016  ostefano:first time I see it tbh, but yup, will keep monitoring
Fri Sep 16 15:54:39 2016  ostefano:there is another thing that changed (again, I am just reporting data points, not stating that they are important/problematic etc)
Fri Sep 16 15:55:20 2016  ostefano:since some 2.1.x I've always had some pending compactions going on
Fri Sep 16 15:55:30 2016  ostefano:I noticed it back then because earlier releases didn;t have that beahvior
Fri Sep 16 15:55:52 2016  ostefano:anyway, 3.0.9 is the first release where I can see that metric going to 0 for all nodes once again

Fri Sep 16 21:26:55 2016  EdwardCapriolo:Hey all. So I was looking at gc_log and gc_warn threshold. I am going to send a patch because the yaml actually describes timeouts that are not actually the default anymore. In the process I noticed that the GC_INSPECTOR does this:

Fri Sep 16 21:27:41 2016  EdwardCapriolo: final static long GC_WARN_THRESHOLD_IN_MS = DatabaseDescriptor.getGCWarnThreshold();
Fri Sep 16 21:27:41 2016  EdwardCapriolo:
Fri Sep 16 21:27:42 2016  EdwardCapriolo:Is there any particular reason we want to copy therese variables vs simply calling the method directly. Is it a performance thing?
