Well - I will use it for myself as a private server - so there won't be more than 30 users... Therefore I think the RAM should be enough... ;-)
I haven't found anything here how to reduce the memory it should use for starting the processes - I think the problem is, that the "upper limit" for the RAM hasn't been set (
AFAIK it is burstable) - but I don't know where I could fix it so that - for example the mysqld - doesn't see more than the given memory...
Any hints for fixing that problem?
