so.. gentleman. one little ol' question. i'm running rancher 2.4.15 on two nodes with v1.18.20+k3s1 (ubuntu 18.04.6) and datastore pgsql 12.9 on a separate server. this rancher cluster is managing two other k8s clusters (one 3 node and one 8 node). it started behaving badly for the last couple of days and i can't seem to pinpoint the cause. overall rancher has up to 800Mbps of traffic with pgsql, and according to netdata, it returns roughly 8 mio tuplets for some specific sql queries... i'm open for suggestions on how to analyze and optimize the database, maybe even clear some traffic, ... or is there some persistence optimizations if i upgrade to 2.5.x
