I apologise if this question has already been asked.
I've taken a server last week on the game space engineer on PC. We noticed while playing that we had some problem of loading and some rollbacks so I checked on the web interface and it says that our server has a usage of 1.6 MB of ram.
On the page where we rent servers and upgrade there is an option to "upgrade" the server's performance (and there is also an option for ram but only for minecraft).
What does the option the upgrade the server adds to it and would it increase it's loading speed or maybe ram for better performance ?
