FOSS gamedev and creative worlds

Running 0.4.9 in dedicated from terminal on a Ubuntu 64bit server with 9 cores and 12GB. I run the server one player logs in it is fine as long as there is one player, get another and it goes to lagging and stops responding till it get's to the point of not responding at all. Any one have any ideas of what I can change/try to get this to perform better?

Do you have any mods that might be crashing the server?

I think it's mobf, so I have to go back and remove it and create an ew map.

Removed mobf and it still is lagging out. I had threads set to 8 because I have 8 cores but then when checking it only uses one cpu......shouldn't it use as many as I tell it too?

Do you have any mods that do something with mapgen?
When Lua code runs then all other threads are locked until its finished; mods like moretrees slow down Minetest a lot like this.

I do have it, I will remove it and test.

If you give us a list of mods you are using, we can probably tell you which ones will lag the worst.

I can see mobf and mesecons that are the most laggy in that list. Homedecor is too, but not as much as the others.

mob framework is off I will turn the other 2 off and see how it goes.......
