13. Performance Tuning of CVS server

For optimum performance CVS server must be running on a stand alone Linux/Unix box.

To get more bang for a given CPU processing power, do the following:-

• Recompile linux kernel to make it small and lean. Remove items which are not used. See kernel howto at http://www.linuxdoc.org/HOWTO/Kernel-HOWTO.html

• Turn off unneccessary unix processes - on linux/unix systems run chkconfig

  ---

  bash$ su - root
  bash# man chkconfig
  bash# chkconfig --help
  bash# chkconfig --list | grep on | less
  From the above list, turn off the processes you do not want to start automatically -
  bash# chkconfig --level 0123456 <service name> off
  Next time when the machine is booted these services will not be started.
  Now, shutdown the services manually which you just turning off.
  bash# cd /etc/rc.d/init.d
  bash# ./<service name> stop

• Do not run any other application processes which are unnecessary.

• Do not leave X-Window running unattended. Because X-window processes consume memory, CPU load and can be a serious security hole from outside attacks. The X-window managers generally used are KDE, GNOME, CDE, XDM and others. You must exit the X-window immediately after using and most of the time you should see command line console login prompt on the CVS server machine.
