Tomcat to WebSphere performance hit

Hi guys,

An open question:

We're having problem with our application when it's moved from Tomcat to WebSphere (Oracle database for both) - any ideas?

I realise this is very hazy, but are there any common things that occur with this type of transition (i.e. moving from Tomcat to Websphere)?

Cheers,

Steve

You couldn't even pin down what kind of problems?

Anyway it's worth noting that Websphere would likely require more memory than Tomcat, given that it has all those extra features. This may or may not have anything to do with those problems.

Hi Paul,

No, we did find that a particular method was getting a hammering, but it's nothing specific to the web application server - basically an iteration. So, the method is nothing special, except that on WebSphere it's taking an awful lot longer to process.

I think the whole application is lagging, but because this one does a lot of work, it's showing the problem.

Essentially, we use a lot of iterations of Lists and that seems a bit slow.

Cheers,

Steve
