Btw. I forgot to mention that CPU load is typically <2-5% on a 32 core server. - Running in stand-alone as testing purposes speed is let say 100% - Running two pieces code separately and connected via IPC methods, speed is also 100%, but IPC latency jitter is a problem - But running two pieces code together (data processing part as 5 additional goroutines) speed decreases to <50% (No lock contention between the two pieces of code, by analyzing more carefully it seems that processing routine gets interrupted in midway)
