    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

      "lss_read_bs":                   2976503344353,
      		 
      "bytes_written":                 1906122153984,

      {nofomat}
      		 
       
      		 
      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
