Lag with 3.5GB ram on a Debian VPS

[minicl55]

I bought a Debian VPS with 3.5GB ram, quad core 3.2GHz processor. At any given time, there are usually around 3-5 players on, all in the overworld. We started yesterday so we're all super early game (none of us have even been to the nether yet).

I'm using the args from here. No MCPC or anything, just the basic Direwolf20 1.0.2 setup. I have disabled Opis as well.

All my my players (along with myself) feel the server is very laggy. Loading new chunks is especially laggy. Why?

First off, ram has nothing to do with preventing lag unless it is at 90% ish used up then the server will lag when it starts to swap.

Second check you connection, and time to latency, and ping by pinging your ip in your command console. Is it bad?

Also on a VPS you don't get the full quad core 3.2 ghz you most likely get a single core. A VPS is a virtual server sharing a real server with other virtual servers.

Install mcpc, it will give a boost in performance, slower boot times is the only downside of it, but let's you enable plugins as well.

Tried MCPC, still slow. I contacted my host and they said that they reserve two cores per person (so two people share a VPS).

The ping time (and time to download a file) is very fast, the only slow part is /tps.

You will want to keep mcpc, it boosts performance. Also you may have a lot of entities somewhere. Get world guard and do /stoplag then /stoplag -c to clear all entities.

Side note, ask your host what CPU model they have.
