LSM throttling isn't working with heavily threaded workloads

    • Type: Icon: Task Task
    • Resolution: Done
    • WT2.4.0
    • Affects Version/s: None
    • Component/s: None

      LSM checkpointing and merging can fall way behind when there are many threads inserting.

      Part of the problem is that writing in-memory chunks to disk is inherently single-threaded.

      Another part of the problem is the heuristic for throttling inserts: what we have just doesn't work once there are more than a few threads updating.
