ES 1.4.4 GC graph and filter evictions

Elastic Stack Elasticsearch
1

Hi,

I have 2 problems:

  1. Look at the attached heap mem graph. Is this Ok? I am worried about why the GC is so active. I have not seen significant performance degradation in query times though. Getting 20 - 50 ms query results. 6.5 million docs.

  2. I have around 1000 filter cache eviction per second. Is this causing the GC to be overly active?

  1. Not a problem, that is what you want to see as it uses and then collects heap. If it went up and never down that would be bad.
  2. Yes a problem! You may want to look at your queries and see what can be done.

hi @debayan I also meet this problem. gc rate is very high while filter eviction is high. Have you found the reason or some solution for this problem?
