sorry for disappearing for such a long time....
eventually we closed our forum to avoid being shutdown by isp. however, we are planing to re-open it tomorrow since nba playoff is coming (our site is a basketball related site). the question i have is, what is a better configuration for XOOPS to achieve optimal performance? currently our configuration is:
1. use persistent connection
2. take out site status block (such as "who's online")
3. disable session
4. set cache on pages (still need to experiment with cache expiration time)
