I'm working on Rescue Agent Simulation, we have a main server that run our code and its programmed in Java. Our server has lag under Ubuntu 13.04, but it run smoothly in Ubuntu 12.10 and 12.04. So my question is, What is the different in these versions of Ubuntu?

Which versions of Java do you have installed? –  Freedom_Ben May 9 '13 at 23:03

1 Answer 1

The default java is java-icedtea. It caused me a lot of problems/freezing for me to.

I installed Sun Java and the performance is drastically improved. You should try with that, just follow the instruction and let me know if you have any problems

What browser do you use? Did you link oracle java with plugins directory? –  DeleteMe May 13 '13 at 10:10
    
I am using Oracle Java 7 , and its working just fine with any issue. –  Sushantp606 Nov 21 '13 at 1:10
    
maybe its also a general performance problem cause by the OS due to the fact that the new OS Version per default has more processes/tasks running. –  konqui Mar 7 at 7:04
