      Description

      Investigate the following improvements we unexpectedly obtained in YCSB runs. The improvement is massive with large documents, but also significant with small documents. The goal is to at least be aware of what has caused this improvement.

      We see these improvements in develop, master and 5.0 builds for mongodb-perf-ycsb-compare-releases jobs.

      The improvements happened with build #582. If coming from WiredTiger they could be because of :
