1. Now this has been merged, the JIRA MUST be updated with fix version
2. Are there any plans to backport to branch-3.3? A retest of the cherrypick
is all which should be needed
Keeping both branches in sync is essential for cherrypicking future work

> The default value of readahead queue depth is currently set to the number of
> available processors. However, this can result in one inputstream instance
> consuming more processor time. To ensure equal thread allocation during read
> for all inputstreams created in a session, we change the default readahead
> queue depth to a constant (2).
