Description
When running a write heavy benchmark, org/apache/hadoop/ozone/om/ratis/OzoneManagerDoubleBuffer.flushTransactions was invoked for pretty much every write.
This forces cleanupCache to be invoked which ends up choking in single thread executor. Attaching the profiler information which gives more details.
Ideally, flushTransactions should batch up the work to reduce load on rocksDB.
