    Description

      Before 2.6.3 initial sync application is single-threaded, while our regular oplog replication is multi-threaded. This improvement request is for initial sync to work that same way.

      It may (significantly) speed up the initial sync process for deployments with multiple active collections or databases to change the oplog application process.
