Why so high ram usage? please tell

Hey guys please tell me why cyberpanel using so much ram. I am currently on cloudways managed hosting with digitalocean server (1GB ram) still it only uses around 300 MB ram. Recently I installed cyberpanel completely fresh without domain or files still 50% ram is used, why ? I was not expecting such poor performance from cyberpanel. I am using cyberpanel with openlitespeed.
