Thank you all for the great pointers. It was monitoring dashboard graph
that mislead to thinking that nodes were problematic. It is not nodes but
high frequency terms queries. Queries that match 50% docs in the index
have high latency of 1-2 seconds.

What are the kind of queries you have? Are they the same 80% of the time?
If yes, they will hit a few nodes all the time.

Hi Rajani,
how many documents do you have in your collection?
The nodes that consistently display high latency, do they have the same
replicas? I mean, are they the only nodes where such high latency queries
can be executed?

Turn on some system monitoring.
For that large a difference, look at IO waits or IO reads from disk, whatever
your monitoring system provides.
Also look at CPU, the CPU utilization should be the same on all the nodes. If
some nodes are lower in CPU, then they are blocked by something else.

It is possible that some of the nodes have either handled zero queries
since the last reboot, or that they have handled fewer queries than the
others, and as
