@JOduMonT it is only a daemon, but sometimes containers are recreated, images are managed and so forth which may use up a lot of server resources temporarily, especially if disk I/O is slow.
To give some reference here, we are talking about the code section from https://git.cloudron.io/cloudron/box/-/blob/master/src/apptask.js#L318 to https://git.cloudron.io/cloudron/box/-/blob/master/src/apptask.js#L340 so something is slow on your system in that area. Not sure how much tinkering you want to do for debugging, but you could stray in some console.log()s there to narrow down the issue. I can also help here, if you enable remote SSH support and send us a mail with your dashboard domain to support@cloudron.io
