[PERFORM] Web server to Database Taking forever
Sometimes when you click on a link on my site to access my postgres database it takes forever for it to connect. You can click this link and see how long it takes.http://www.3idiots.com:8080/example.../wantedlist.jspIt doesn't do it all the time. Sometimes its really fast. I can't figure out what is wrong. If I go on the server where the database is I can connect and run queries with no problem. I can also access the database from Access and run queries with no problems. It is only a problem when you come from the web. Tomcat and apache are both working. You can see this by going here http://www.3idiots.com:8080/example...moviesearch.jspI am using psql (PostgreSQL) 7.2.1tomcat 4.0.1apache-1.3.9-4Redhat linux 6.2Does anyone know what I can check to see what is causing this. It seemed to have happened all of sudden one day. I don't know what could have changed to cause this. I have rebooted the server and it still happens. Any help will be greatly appreciated.Also I need to add that I never get an error message. It just sits there for quite some time. Eventually it will work.

Scott, Sometimes when you click on a link on my site to access my postgres database it takes forever for it to connect. You can click this link and see how long it takes. http://www.3idiots.com:8080/examples/jsp/movies/wantedlist.jsp http://www.3idiots.com:8080/example.../wantedlist.jsp Sounds like it's a problem with your Tomcat and/or JDBC setup. Try the pgsql-jdbc mailing list for help. -- Josh Berkus Aglio Database Solutions San Francisco ---(end of broadcast)--- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match

So do you still think its Tomcat or the jdbc driver? a suspect might be the nature of JSP. on the first hit, JSP is converted to a Servlet, the compiled and loaded by Tomcat. consequent hits would be fast. first one is always slow. how did you connect to the database? -- stp, eyan inhale... inhale... hold... expectorate! ---(end of broadcast)--- TIP 2: you can get off all lists at once with the unregister command (send unregister YourEmailAddressHere to [EMAIL PROTECTED])

Are getting an unnaturally large number of processes or threads or pooled connections or what-not somewhere maybe? Have you tried logging output from something like top or iostat to see what's going crazy when this happens? Just wondering. ---(end of broadcast)--- TIP 6: Have you searched our list archives? http://archives.postgresql.org
