Weird. In one of my Go explorations I wrote a naive trade algo backtracker which ingested 100,000 datapoints per second from SQLite on commodity hardware.
I'd expect something highly specialized such as GRPC server to perform better.
True. But in my case the code also distributes these datapoints to multiple threads, computes technical indicators and simulates tradings while gathering statistics to finetunne parameters.
The only optimization I've done was to ditch maps wherever I could. They were dominating flamegraphs.
This is why I expected GRPC to perform better. But I agree it depends heavily on what's being done.
