    Description

      Big performance drop (>80%) from git: a7338c4 on single-threaded MMS workloads. Same build was marked red for Geo and Misc cases but there only one test failed for single-threaded cases and the drop was much smaller. I think it's safe to ignore that and just focus on the MMS cases.

      The commit that caused this was a wiredTiger check-in. WT team is aware of this drop so I am putting WT as the component for this ticket so they can pick this ticket up.
