threadLocalItems from
workQueue at once and excutes them sequentially.threadLocalItems - the number of items this thread should dequeue
from the work queue at one time. Setting this value too high can
result in a loss of concurrency; setting it too low can result in
high contention on the work queue if the time per task is also
low.Copyright © 2012. All Rights Reserved.
