      The following perf tests show regression between Feb 13th and Mar 9 runs:

      • Parallel pop stress load time
      • Unstable performance with overflow-130k btree throughput for read/update
      • multi-btree-zipfian read throughput
      • perf btree jobs
      • medium and small lsm throughput
      • update checkpoint btree and lsm throughput
      • logging variants zerofill
      • evict btree and evict lsm throughput

      This seems to have started between
      Feb 13: https://github.com/wiredtiger/wiredtiger/commit/0fd1d61d8e3cb2d811e8374d4b34fd0a6a67435a
