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?
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
