Lags on Linux

[jensakaa]

I'm using an 3GB RAM, 3 CPU  3,3GHz cores VDS.

The vanilla server with caves lags a lot even with 2 players online. Also the server uses only 1.5GB of RAM. Thats not the Internet problem, as the ping is okay.

 

What could be the problem?

Lots of factors, use a profiler.

@CarlZalph,

I think the problem is that the server makes one of the cores go ~90% loaded, while other just stay ~30-40% loaded.

Any clues?

Yes, because DST is mostly written in lua it's largely bound by your single core performance.

@nome,

So nothing can be done with this?

There are lots of things you can do to improve performance, but DST is always going to be bound by your single core performance, taking advantage of 16 cores or something like that would require a complete rewrite (or lots of tiny worlds joined together like caves + overworld).
