Hi All, We are doing query performance test with different soft commit intervals. In the test with 1sec of soft commit interval and 1min of soft commit interval we didn't notice any improvement in query timings.
We did test with SolrMeter (Standalone java tool for stress tests with Solr)
for 1sec soft commit and 1min soft commit.
Index stats of test solr cloud: 0.7 million documents and 1 GB index size.
Solr cloud has 2 shard and each shard has one replica.
Please find below detailed test readings: (all timings are in milliseconds)

As theory suggests soft commit affects query performance but in my case it
doesn't. Can you put some light on this?
Also suggest if I am missing something here.
