How to allocate more memory to FeedtheBeast Server?

[Jemjem787]

I must look like a complete idiot posting this, but can anybody help me?

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

java -Xms512M -Xmx1G -jar ftbserver.jar

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

I would recommend adding "-server" to the command

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

 

[glasspelican]

yep, I place it at the start of the list

java -server -Xm....

 

[Jemjem787]

What is the point of doing that though?

 

[glasspelican]

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

I cant seem to get it to work for me, does this still work?

 

[glasspelican]

Does what work, Adding more memory or the -server tag?

what is your question?
What problem are you trying to solve?

 

[Mistereddy]

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.

 

[glasspelican]

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

java -version

 

[Jemjem787]

i7-3770k, 8Gig ram. windows 7 home, 64bit. Allocated 1gig-3gig.

java -version brings up

java version "1.7.0_10"
Build 1.7.0_10b18
64bit server vm (build 23.6-b04 mixed mode

 

[Mistereddy]

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)

 

[heggico]

You do realise that the 32 bit version of any windows can only use around 4GB of ram?

 

[glasspelican]

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

 

[Mistereddy]

You got to be shitting me.... -.-" no i didnt know that... ugh.. well, i'm going to upgrade then...
