    @gatorsmile can you link the ticket about the perf regression? I imagine 
you would be seeing perf regressions in cases where partition counts are less 
than total cluster capacity, as this has the chance to reduce parallelism there.
    
    Also, is there a specific suite of perf-testing benchmarks that I should be 
running here that are used in testing releases?
