I've been running a Tekkit 2 server for a few players for a while now without any problem and just 1Gb memory allocated. Now I'm setting up a Tekkit 3 server and while testing it myself, I keep getting the dreaded "[WARNING] Can't keep up! Did the system time change, or is the server overloaded?" msg. The server log doesn't show any errors regarding mods or starting up and this is with a new world and nothing has been built yet. So before reporting this as a problem to be fixed, I was wondering if the performance requirements have been drastically increased with the new mods? And does someone know if (and if so, how) I can check memory allocation for the server in a similar way as the client can with F3 ingame? I tried to search for this, but all I can find about is client performance tweaking.
