I have very different time for each simulation run. I have series RLC circuit model, and first simulation time is 22 minutes. In next start of omedit this circuit simulation time is 90 sec. And after next start, simulation running 45 min. and not finished. My system is Debian wheezy, open-jdk6, Intel Core 2 duo, 4GB RAM, kernel Linux ntb1 3.2.0-4-amd64 #1 SMP Debian 3.2.39-2 x86_64 GNU/Linux, or PREEMPT_RT and no change in simulation speed. I need help. I don't know where I have a problem. Thank's for help
