We have our field data configured at 40% of available heap size (which is currently configured to 122 GB) which comes to 48.8 GB. But we are seeing evictions at a number of 835 and field data reaches 47.7 B easily.
Our heap usage under this condition is at 95% and we see long running full GCs with G1GC configured. ALso the CPU usage went upto 80% during this time.
I wanted to know how much load can every eviction cause on the system.
