after about 10m after staring my application the CPU increases to ~20%.
Here are the Garbage Collector stats
. What I can see is that the CPU usage increases when at that point when the YGC increases way faster than before. It starts at Timestamp 706.3
In this chart you can see that Eden space
is not used and Old generation
is not modified anymore. If I force the application to do something, the CPU is going down to ~2-3% till Eden space
is empty again
