Journal thread fetch entry from queue cost too much time on acquireInterruptibly

**BUG REPORT**

***Describe the bug***
The bookie configuration list as follow.
- 24 cores
- 48 bookie-io threads
- 1 journal directory on NVME SSD
- 3 ledger directories on NVME SSD
- journalQueueSize is 10000

The write throughput keeps on 500MB/s.
When read request increase and the read throughput reaches about 600MB/s, the journal queue will be full for a long time. I check the journal sync latency is low. I print the stack of the bookie, and found the BookieJournal-3181 thread keeps on acquireInterruptibly in ArrayBlockingQueue.poll operation.

Does anyone has any ideas for this situation?
