Hi folks,
I got a sensible Jetty and JSPWiki configuration and give it a try for
the next week.
If it works out
+) I upload an archive to enable some field testing
+) I have a look at patching the 2.8.0-beta-1 code base - in an ideal
world I'm able to create the distributable from the ANT build.
And I have one question - after starting JSPWiki there is a three second
delay before the first page is rendered. I attached a profiler but
couldn't spot anything unusual. I know it is a rich men's problem but
I'm interested in really good startup time and wonder were the three
seconds are spent.
I've been using JSPWiki and Jetty for about five years now in a
standalone application (Ceryle) with no specific issues as regards
performance. Startup delays are normal and also occur when using
JSPWiki on Apache/Tomcat (and are similar with Jetty to an Apache/
Tomcat installation). These are due to a variety of startup tasks
such as reading properties, creating the various managers, building
lists and indexes, as well as the normal housekeeping of any web
application. If you have installed any additional features or added
features to pages (i.e., anything that requires the page upon
instantiation to perform tasks) will also cause a delay.
If you're really curious you could instrument all the JSPWiki
managers with System.err.println() calls at the start and end of
constructors and methods, which will get written to the server logs
as things start up. If running from a standalone application these
get written to the console, so you'd be able to actually watch
things happening live -- it's rather informative to see in what
order JSPWiki fires things up. I do this sometimes when debugging.
In summary, there is nothing unusual about any of it.
