2.1.1 nfs_async_timeout
Description
The nfs_async_timeout tunable controls the duration of time that threads executing asynchronous I/O
requests sleep before exiting. If no new requests arrive before the timer expires, the thread wakes up
and exits. If a request arrives, the thread wakes up to execute requests then goes back to sleep.
Tested Values
Default: 6000 Milliseconds (6 Seconds)
Min: 0
Max: 360000 Milliseconds (6 Minutes)
Note: If the tunable is set to a value greater than 360000,
an informational warning is issued at runtime. Any value
greater than 360000 is outside the tested limits.
