I've been trying to get our jetspeed based portal up to acceptable response times (<
1sec), and since the topic has come up several times on this list I thought I'd share
some of what I've come up with. Additionally, I'd love to hear any corrections or
additional tips you might have. :-)
A quick overview of our app: We're working with 1.4b1 still, using role based psml,
stored in a db. We use velocity almost exclusively. Content is grouped and organized
by tabs; e.g. Home, For Staff, Employment, etc... Some of these tabs have sub-tabs.
Each pane has one or more portlets associated with it.
Customization is controlled by a turbine permission called PortletConfig. If you have
it you can customize everything, otherwise you can customize nothing. Our main
slowdown was caused by checking for this permission. For each tab, page, pane, and
portlet we were checking the user for this permission using a helper function that
would return a list of all a user's permissions given a username. The function was
written to be a convenience, and to be used sparingly; it takes a username, retrieves
all the roles associated w/ said name, and iterates through those roles, building a
list of permissions. This list, once retrieved, wasn't being stored in the session or
anywhere so it was being called numerous times per page. Obviously this was pretty
damning. :-)
My quick fix was the simply change the PortletConfig permission to a Role since only
"admin" had the permission anyway. There are other solutions but this one was such a
benefit it was good enough for now.
Attached is a document which is basically a checklist of things to make sure are set
in various .property files before moving to production. If your files are generated
through ant/maven/whatever this will be of less use. If anyone notices something I
have forgotten, or see something I shouldn't have changed please point it out: I'm
not an expert at configuring Jetspeed by any stretch of the imagination. The jist of
the file is this:
Turn on module and template caching.
set appropriate max # of db connections.
set appropriate modification check intervals.
Comment out stuff we don't use.
Some of the things I recommend commenting out break some of the admin only portlets we
don't use. FYI. All these apply to 1.4b1; some things may have changed since then.
Cheers,
stu
