Hi, what may you suggest as the most optimal postgresql.conf to keep writing as stable as possible?.. What I want is to avoid "throughput waves" - I want to keep my response times stable without any activity holes. I've tried to reduce checkpoint timeout from 5min to 30sec - it helped, throughput is more stable now, but instead of big waves I have now short waves anyway.. What is the best options combination here?..
