    Description

      Currently when using vnodes, repair takes much longer to complete than without them. This appears at least in part because it's using a session per range and processing them sequentially. This generates a lot of log spam with vnodes, and while being gentler and lighter on hard disk deployments, ssd-based deployments would often prefer that repair be as fast as possible.
