you have a file named ServerStart.bat or ServerStart.sh on mac or linux
open in your favourite text editor

it will look something like
Code:
java -Xms512M -Xmx1G -jar ftbserver.jar

-Xms512M Min heap size in ram
-Xmx1G Max heap size

I would recommend adding "-server" to the command
Cheers

what do you mean by adding -server to this command? Just put it at the end so its like ftbserver.jar -server

The server tag tweeks the java garbage collector and compiler
The server will start slower, but run with less lag, and use a bit less ram

Well my question is: Does Ftb still work by adding more memory in the way you described? because for me it doesn't.
Why? well i just had a computer upgrade with 32 Gigs of ram on it. and i want to make use of it :)
i know it doesn't need it. but i still lag without the extra ram... and it's not lagging because of my CPU or my vid card. that i know for sure.

There can be any number of problems that can cause a server to lag, not just ram or cpu
what cpu do you have? Operating system?
I have observed that giving a server to much ram can cause issues as well, try it with 5Gig
can you open the command prompt or terminal and run
Code:
java -version

i5 dunno which exactly, it runs at 3.2 though. 32 gig ram, windows vista, 32-bit. (the 32 bit doesn't seem to be the problem though).

java version "1.7.0_09"
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) Client VM (build 23.5-b02, mixed mode, sharing)

The 32 bit version of java can only use 2G of ram, using a 64bit os also lets it process more data in a clock cycle
you are also defaulting to a client version of the jvm add the -server tag detailed above
