There are a number of advanced configuration parameters that can be set to modify LISTSERV's behavior and/or tune it for better performance.  The most common parameters are found in the Site Configuration Keyword Reference document.

A tuning guide for high volume sites is available upon request; please contact L-Soft's support department at support@lsoft.com for a copy.
