We have run into an issue, where the survivor space fills up to the max pretty quickly, and things start running very slowly as the day progresses.
We are using jdk1.6.0_16, and here's the JVM parameters the server runs with:
-Xms12g -Xmx50g -XX:MaxNewSize=8g -XX:NewSize=4g -XX:SurvivorRatio=6 -XX:MaxPermSize=128M
Here's how it looked like at one point:
|Non Heap Memory||176||132||23||111||63|
I'm not really sure if it's the survivor space that's causing the slowness or nor, but if so, what should I set it to, to get better performance? Or, can I just get rid of it, and let the system handle it.
Any assistance/insight would be very much appreciated.
