Check out the "LINT" file in /usr/src/sys/i386/conf for more info. These settings are mentioned in the Apache manual for performance tuning your kernal. Once the setting are made, config, compile, and install your new kernel and reboot. -- | John Lucas jlucas@jnet.vi | | Information Technology NIC Handle: JL423 | | University of the Virgin Islands (809) 693-1216 | | St. Thomas, VI 00802 http://www.jnet.vi/jlucas.html |
