After some stress tests and other tests I have decided that for wordpress the best http server is OpenLiteSpeed especially in backend and generally with chaching management. So I want to ask if someone has find the "best" configuration on OLS in aaPanel and which plugins are necessary for sure working in a heavy wordpress site. Maybe the best plugin for this is LiteSpeed Cache but with what settings/configuration? Additionally, what else do you suggest for this scenario? Are you agree with OLS for wordpress?
