Are you saying that performance improved right after your maintenance, but then degraded again?
I would start the investigation in your access.log. The last number on each line is, I believe, the time it took to serve the request. Are those numbers in line with the response times you’re seeing on the client side? If not, if they’re shorter, then the investigation probably moves to your network. If they are in line, then it’s time to turn up the server logging level to DEBUG so you can see the SQL requests and figure out some timing there.
Got it !
It helps a lot. Effectively, with this access log, it appears there’s no problem. Our instance is installed on specific network (dev) and we can access it from another network… and this one takes times… I check the access on same times on both and saw the difference. Network issue then… glad to know that our sonarqube is working well then
Thanks for your help
