Hi, I am befuddled by GC SW times on several seconds (seen 20s once) in the metrics page for our app. There are several things that are strange but perhaps I am misreading it. The same metrics page reports Max Total 35 MB out of which 1 MB s swap the rest RSS. The response times on the service is has 99% ~400 ms which is not good but 95% is ~120 ms usually. The app reloads an in memory cache as needed using atomic,Value as a holder and the size is no more than a few thousand at any given time. Basically a map with pointers to simple structs and lists with pointers to the same structs to allow for some simple access scenarios.
Now I haven't profiled the app yet but even in a very pathologial case it seems as though the GC would be able to keep up easily with such little amount of memory being used. Granted this is a Standard 1x dyno but even so once the machiine is stopped the GC should be able to complete it's work in a very short time given the low used memory. Has anyone seen this as well? Could the Go metrics on Heroku simply report erroneously? Perhaps a couple of orders of magnitide?
