# Apply recommended OS-level tuning

The [PingDirectory Server Administration Guide](../pingdirectory_server_administration_guide/pd_ds_amin_guide.html) makes several tuning recommendations to help ensure software runs smoothly.

These include:

* Configure file descriptor limits.

* Configure process limits.

* Apply recommended filesystem tuning.

* Disable filesystem swapping.

* Configure filesystem event monitoring limits.

* Tune the I/O scheduler.

* Tune memory management.

* Manage OS-level environment variables.

* Configure the system to allow the PingDirectory software to listen on privileged ports while running as a non-root user.
