> On a server with ~5.5TB of data, the maintenance manager scheduler thread has gotten quite slow. The thread takes many tens of seconds to pick a maintenance operation, and then the actual operations take only a few seconds to run. So, the actual "duty cycle" of those threads is quite low, and compaction/flushing falls behind.
