I am new at this and would love some help. I am running ftb server on a mac mini (direwolf).

When I launch the server by simply clicking on the file ftbserver.jar, everything works well. I get an occasional warning cant keep up message but no lagging with play.

When I launch the server with a shell command, I get lag and multiple continuous warning can't keep up messages. My shell script is simply
java -Xms5020M -Xmx5020M -jar ftbserver.jar

I have tried increasing and decreasing the memory setting but there is still lag either way.

How is ftb launching differently when you just click the ftbserver.jar file? I am not even sure how much memory is allocated to the server this way.

Any help appreciated. Thanks.
 
First, how much ram does your mac mini have, and second, do you have a console log that you can provide from the server?
 
Thanks for the response. The Mini has 8gb. The server runs fine when I run it by clicking ftbserver.jar. I have no idea what the java settings are when run this way.

When I start it with any script giving Java memory parameters, I get the errors and the server lags. I have tried the following all with similar results.
java -Xms5020M -Xmx5020M -jar ftbserver.jar
java -Xms128M -Xmx5020M -jar ftbserver.jar
java -Xms512M -Xmx1028M -jar ftbserver.jar

The log file is linked. java -Xms5020M -Xmx5020M -jar ftbserver.jar

I don't know whether or not you use the ftbserver.sh, but try editing that with TextEdit and putting the following code in:
Code: 
java -jar -Xms1G -Xms3G ftbserver.jar
//Note: If you don't want the window, and just the console open, add " nogui" to the end of the above code
//If this doesn't work, your java version is for x86, you need to upgrade to 64 bit
 
I have learned a little bit but still do not know the answer. The default launcher for the ftbserver.jar is jarlauncher (mac). When I launch my server this way, there is no lag. I do not know any of the parameters used with jarlauncher. When I try to launch from a shell scripts similar to the one you listed above, there is significant lag. I am uncertain what the difference between these two launch methods is. I would like to manually set RAM utilization but no setting that I have tried is better than the jarlauncher method.
