Very strange performance problem
Hi all
I have a problem with my Tapestry application. Its finished and it works,
except, after I navigate for a while, the application slows down to a crawl
and becomes unusable. I click on links, I watch the browser status bar
slowly fill up and nothing happens. Tomcat doesn't show any errors
whatsoerver.
I believe this problem is not external do the application because the same
thing happens on my laptop and on my companie's server, two completelly
different environments.
Could anyone give me a hand to find whats happening? We're suppose to go
into production and this is the only thing stopping us.

Create a launch configuration for Tomcat, something like this:
Main class: org.apache.catalina.startup.Bootstrap
Classpath: ${tomcat.home}/bin/bootstrap.jar
Parameters: -Dcatalina.home="${tomcat.home}"

Another way is to set up the java opts:
JAVA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n $JAVA_OPTS"
Then in Eclipse set up a remote java application. Start up the application, have Eclipse connect to it and the put breakpoints anywhere you like.
See attached jpeg, if it can come through.

Use a plugin for managing tomcat.
I use the "Sysdeo Tomcat Plugin", which launches tomcat in debug mode by
default.

I'm running it out of the box. Apart from friendly URL's I have nothing
configured.
How can I run a web application in debug mode in eclipse? Don't I need a
plugin for that?

Run it in eclipse in debug mode?
Do you have caching disabled?

I'm replying again because I received a virus warning from the mailing list:
Java doesn't even show on top. My pages are pretty simple: I call a stored
procedure, I retrieve values and set them on a model and then I display the
model on the template.
Is there a way to profile this application?

Are you watching the memory and cpu usage of javaw.exe? My instinct
says you're creating objects without destroying them, or there is a
inf loop somewhere (or both).
