    Description

      It is observed in a magma deployment environment that there is a variance in bandwidth usage reported by magma stats compared to OS iostats.

      The specific case consists of seq index scans. It should be ideally sequential reads and shouldn't incur wastage due to block alignment.
      IOStats reports: 50MB/s while Magma report 25-30MB/s

      Details are provided in the linked CBSE.
