Does the slowdown occur at the same time as a higher than normal volume of hits?
Consider getting all of the data and dumping to variables *before* formatting. If using multiple connections to the DB try reducing to a single connection. If using a single connection try implementing a DB connection pool.
Other than those things not much comes to mind at the moment.

Dear Sirs, I wonder if anyone had anything similar before. I'm running some JSP/Java Bean websites under Tomcat (on one PC as a stand-alone server, on another in connection with Apache).
The website is a dynamic (3-tier architechture) connects to MySQL
database to get the content to display any page (around 3-4 connections
per page).
Normally the performance is really good, but about once a day it gets really slow (around 1-5 minutes to display the page). It also recovers autocatically to normal response time when you simply wait 5-10 minutes.
Any ideas?
I'm running Tomcat 4.05 with Apache on RedHat 8.0 (one PC) as well as Tomcat 4.127 on SuSE 9.0 with MySQL 4.015.
I'm closing all db-connections in JSP/JavaBeans, so I don't think it's a db-issue.
I'd highly appreciate any help on the topic.
Thank you very much, Roman Zhovtulya
