Do sharding & flush hot threads indicate slow indexing?

Hello everyone,

I notice in my hot threads that it's spending a lot of time in write related sections of code. Also, I'm experiencing slower indexing rate than usual (45% decrease)

Here's the output: https://gist.github.com/vinicioflores/fef2cd267224b1532c933eed57b4831c

Please help,

Regards,

Hey

Are you running on a slower disk? Is it possible that you are by accident limiting write speeds, so that merging blocks indexing to not write too much data so that merging cannot keep up?

How would you advice me to check this from ES cluster ? Any metric I can monitor to find out
