Is it normal to have longer bulk\_write time if I increase the refresh\_interval to say 300 seconds?  
I have noticed an index bulk\_write is taking more than 4 seconds. Not sure if this is normal or cause for concern.

I get the time from periodically calling GET /\_cat/tasks?v&detailed=true.

Is that when you are increasing the refresh? Or is that just how long you are seeing the bulk take?

I'm seeing bulk write to an index with long completion time. That index happens to have refresh\_interval set to 300s.  
I did not see this before. We recently increase the refresh\_interval from 120 to 300.  
Hence this question.  
It might be something else, but just to check if this is a known behavior before going further.

What version of Elasticsearch are you running?
