We have a few Go processes with high memory usage. For one in particular, while it's been higher in the past (~150GB), we're sitting at 40-80GB per node right now.

The busiest node traffic-wise had average GC time over the past 20min of 3.4ms every 54.5s. 95th percentile on GC time is 6.82ms.

That node is sitting at 36GB in-use right now, and has allocated (and freed) an additional 661GB over the past 20min.

Can't really speak to how fast this is vs other environments, but it's smooth sailing overall. /shrug
