observed increased response time after upgrading mongo-ruby-driver from 2.17 to 2.19

      We're currently running:

      • Mongoid 7.0.13
      • Mongo ruby driver 2.17
      • Atlas replica set 5.0.25 (M80) 

      I upgraded the version of the mongo-ruby-driver to 2.19.3, with the only changes being updating a few places that used bulkWrite to ensure not to call if we were passing an empty array.

      Our P90 response time is around 800ms and when I deployed this change, they consistently went up to over 1800ms, and when this change was reverted, they dropped back to expected levels.

      Many thanks
