here are some things that can potentially help:

1. disable all the chunk loaders

2. disable buildcraft stuff, it's pretty laggy compared to redpower stuff.

3. buy more ram!

4. disable mob spawning.

5. disable the nether. or at least disable nether ores.

6. wait, hamachi???

7. don't try to play with the same machine as the server.

8. disable watch of flowing time.

9.  turn off any machine you see.

10. if all else fails, give up on tekkit and make a vanilla server instead.
