The +A option allows you to specify the size of the I/O worker thread
pool.  For moderate and high workloads that involve the local file
system(*), you'll likely see a performance improvement by using it.


(*) All UNIX variants that I'm aware of will ignore any request to
perform asynchronous I/O on the local file system unless you explicitly
use the async API.  And even the async API doesn't have async versions
of some system calls like unlink(2).
