| Description |
|
The config upgrade process is using sync-ed cluster connections to back up some collections. The process uses batched inserts to speed up these copies but at the end of each batch on a sync-ed cluster connection we issue a full fsync. It may be faster, and achieve the same goals if we lower the write concern done at the end of each batch to a w:j. |
