I don't know how you'd define "light load", but I have a few services that average about 100rps. Only 1 active container most of the time, they're allocated 128MiB RAM, with a p99 utilization of 55%. They don't have any GC config or special optimization - just operating with regular JSON POST requests, making MongoDB queries

Go just does incredibly well in these kinds of conditions. The only reason we allocate 128MiB is because that's the minimum Google Cloud Run allows - we'd probably go for 64MiB on most systems otherwise
