Thanks a lot for your time to respond for my clarifications.

We are having two environment,
ENV A and ENV B ( Both same capacity of RAM ( r5.2xlarge  and same number of
shards and replicas type (NRT) for the collection)

ENV A -  it is having a collection which is optimized ( segment count 1 and
numdocs = maxdocs ) it is used only for Search request. No delta updates are
being triggerred.


ENV B - It is having same collection copied from "ENV A" and continues DELTA
updates in progress so it is used for Indexing and search request. Indexing
using KAFKA connect plugin that uses SOLRJ with
solr.commit.within=300000 ( milli seconds )


We are comparing performance between those environments for search request
using automation test running with bunch of queries.

Regarding search warmup:

    <query>

        <maxBooleanClauses>10000</maxBooleanClauses>

        <filterCache class="solr.FastLRUCache"

        <cache name="perSegFilter"
