The background compaction server may need to open dhandles to compact the tables. This can create contention as the dhandles are created/released under locks. 

Tasks:

• Create or reuse a test (many-dhandle-stress.py could be a candidate) to assess the impacts of the background compaction server where there are many tables in the database.

Definition of done:

• Relevant statistics are measured (throughput, latencies, ...) and compared when the background compaction is enabled/disabled.
