Use the Tuning tab to adjust performance settings:
This setting determines the number of times NFS Client tries to reach an NFS server.
This setting turns on an NFS v3 performance enhancement. This enhancement detects when NFS is reading a file sequentially rather than randomly as in a database file, and prompts NFS to retrieve into the data cache several data blocks ahead of the data you are currently reading. If you notice poor performance when using a database or other random-access file, turn off asynchronous readaheads.
You can specify the number of seconds an automounted file system remains connected after all files on it have been closed.
