Re: [go-nuts] BuckHashSys growth

Thanks much. Memory allocation does indeed appear 'spread out' as a result of some recursive function calls of varying depth that get called during serialization, and a variety of code paths that can trigger the serialization, at least after a quick skim through portions of very large /debug/p

While investigating climbing memory usage for one of our services, I've noticed a continual increase in the BuckHashSys metric from runtime.MemStats ("bytes of memory in profiling bucket hash tables"), from 0 to ~2.5GB in the span of about 20 days, and no signs of stopping. This is an applicat

The documentation is correct. The current runtime.GC() implementation invokes a Stop The World (STW) GC that completes before runtime.GC() returns. It is useful when doing benchmarking to avoid some of the non-determinism caused by the GC. On Tue, Nov 29, 2016 at 1:15 PM, Ian Lance Taylor wrot
