Following up on the improvements in This is far better than before the upgrade with Please loop me in to any investigations here; now that TIG-3599 has been done we can revendor the C++ driver into genny very quickly and easily, so can very tightly iterate with y'all on this. |

After extensive testing, I was unable to replicate this issue. Because PERF-2203 is already over a year and a half old as of writing, all people associated with this ticket are no longer with the company, and none of the current members of the perf or Genny teams have encountered this issue, we have decided to close this ticket as "Gone Away". If anyone encounters this issue, please re-open it and notify the C Driver team. Please share any and all steps necessary to recreate the issue. I detailed how to recreate my testing in Confluence here: https://wiki.corp.mongodb.com/display/DRIVERS/Lock+Contention+Issue+In+The+Mongo+C+Driver |

We are also seeing a lot of samples in mc_tpld_modify_begin, see comments on the related perf ticket. Posting in this ticket in case they're related, but can spin out a separate ticket if preferred. |
