Tekkit running laggy on my server

[cheiron92]

I have a VPS with two cores of a Intel Xeon and 4 GB RAM. The Tekkit classic version runs very good on this, but I cant get the current server to work properly. I have debian 7 with Oracle Java 7 installed and run the server that I found on the Tekkit website main page. I started the server by the following command:

java -Xmx3G -Xms2G -XX:+UseConcMarkSweepGC \

-XX:+CMSIncrementalPacing -XX:ParallelGCThreads=2 -XX:+AggressiveOpts \

-jar Tekkit.jar nogui

Just walking around on the server is no problem, but the animals just stand still and if you hack a block you have to wait around ten seconds before the block actually disapears and drops. Placing blocks goes without a problem. The server also does not feel laggy, you can run around without a problem.

Has anyone a clue why Tekkit does not run properly on my server?

What's that second line do?

Also, are you running the server from your computer? Do commands lag?

Which version of Tekkit are you running?
