Just did a quick comparison of the latest Go1.12 beta 2 vs. Go1.11 in terms of STW pauses. The results are good!

When the system is highly loaded, I use runtime.ReadMemStats to collect GC pause data and plot the results of the first 120 GC cycles.

The system being tested is my open source Raft library available at github.com/lni/dragonboat
