    Description

      In 7 indexes bloom filter test for build 5177, I can see that the 2 stats approximately match rbps and wbps from html report.

      rbps 300-400 MB/s
      wbps 100-150 MB/s

      For 10K index incremental build test, the number seems to be off, especially for lss_read_bs.
      

      rbps read 150 MB/s
      wbps write 125 MB/s
