I recently upgraded to ELK 5.1.2 stack. I am trying to execute a simple search on all indexes (last 7 days filter) from kibana. I found that ES is taking a an average of 15 seconds to search an index. Following is a screen capture describing the _msearch taking long duration for an index:
As you see above, the _msearch is taking 15 seconds to search an index. This is a major problem and is blocking us from moving to production environments.
Can anyone let me know what is going wrong.
