You should try a tool like ProxySniffer or a plugin for FF or IE to see
why your page performance is that bad. We had some problems in our
project concerning included css and js-files. You should be able to see
who's "responsible".

Hi
I have a JSF application with some quite unusual performance problems.
Loading pages in IE7 takes 4 times as long as in Firefox (v2.0.0.11).
When I test the application locally, response times are good, and pretty
similar for IE and FF. When I test our actual deployment, pages take on
average 6 seconds to load in Firefox, and about 23 seconds in IE7. The
pages
that are being rendered are very simple, with perhaps 10-12 links and a
handful of form fields. Much as I'd love to tell our users to just use FF,
most of them use IE and making them switch is not an option.
I've already looked at the performance page on the MyFaces wiki, and
implemented the server-side tips there.
I'm using
MyFaces 1.1.4
Tomahawk 1.1.3
Firefox 2.0.0.11
Internet Explorer 7.0.5730.11
Are there any other obvious areas anyone can think of to target?
One thing that comes to mind is that Firefox might be caching some resources
while IE is not caching them, and so repeatedly fetching something. This
difference might not show up when the server is local, but be much more
significant when the server is remote and more heavily loaded.
I suggest you enable logging of all requests on your server and then compare
the list of URLs fetched by firefox with the list of URLs fetched by IE for
the same page. This can be done on your "local" server, not the remote one.
I would also enable the "live headers" plugin in firefox and have a look at
the http headers for pages, making sure that they have the appropriate
caching headers set.

Simon
