Hi we are running a Postgresql Database 9.4.18 and we are noticing a high CPU usage. Nothing is critical at the moment but if we were to scale up more of what we are doing, I feel we are going to run into issues. It is a 2 x 6 core machine, 128GB ram, Raid 10 HDD The iostat metrics for the HDD look minimal < 10% util Available memory seems to be good. The CPU utilization is what bothering me user 5-7% sys 50-70% - seems high wa <0.5% So trying to troubleshoot possible high cpu: Number of concurrent connections averages 50 to 100 - seems high although we max at 200. No long running queries Streaming replication to backup server High update tables - we have about 4 tables that have a high volume of updates High update rate is what I am thinking is causing the issue and I found possibly setting fillfactor to a lower default which the internet says you need to do a vacuum full which I am trying to avoid but if it needs to be done we can schedule it. Just want to make sure if I am chasing the correct rabbit hole. Are there any statistics I could run to see if a setting change would help. Best, Scott -- T: @Thaumion IG: Thaumion Scottix@xxxxxxxxx
