Does it mean in Wicket 1.x there is code that streams static
resources? That's interesting. Can you point me to the relevant
class or method?

We don't recommend putting the Wicket servlet at /*, you can find it all over the mailinglist and on the WIKI. This is because the servlet then has to serve *ALL* things in the application context, provided you don't tweak the web.xml to do otherwise. Apparently they serve a lot of static things from the root context.

Re: [Wicket-user] low wicket performance - intensive file system usage
I think I found the cause of our performance problems - we map wicket
servlet to /*. If I change it to "/app", things become much much faster.
The problem is that our customer doesn't want to have redirect on the
main page, and at the same time this page is not static. Any suggestions?

Re: [Wicket-user] low wicket performance - intensive file system usage
You dont use head of 1.3 i guess? because storePage doesnt do much there any more. But i guess if you see CPU time it is really the serialization you see not the save to disk. can you drill it down a bit more? johan On 2/13/07, Andrew Klochkov <[EMAIL PROTECTED]> wrote: Hi Recently we launched some simple webapp written in wicket, but performance is obviously low.

Re: [Wicket-user] low wicket performance - intensive file system usage
This is very strange.
We are know about the FilePageStore.storePage performance issues and
johan is working on optimizing that.
but CompressedPackageResource shouldn't take 30%. Definitely not. caches
the resource so the serving should be immediate. Unless your machine
runs out of memory, in that case the cache is evicted.
I'm not sure but i think there was a memory leak in 1.x lately, are you
sure you're using the latest version?
What's the configuration of your server?
Btw. You can try to use HttpSessionStore to see if it makes serving
pages faster
(in your application class
protected ISessionStore newSessionStore() {
return new HttpSessionStore();
}
)

[Wicket-user] low wicket performance - intensive file system usage
Hi Recently we launched some simple webapp written in wicket, but performance is obviously low. Even simple pages are being loaded too slow. I tried to dig into it using profiler and found out that wicket takes 67% of CPU to work with file system. Main points of low performance are: 1. wicket.protocol.http.FilePageStore.storePage eats 25% of CPU 2. getting resources using CompressedPackageResource eats 30% of CPU How can we improve it? Why does wicket save all the pages in files, why not to use http sessions? And what can be done with resources? I guess the browser doesn't cache them and it takes to long time to get them from jars. -- Andrew Klochkov - Using Tomcat but need to do more? Need to support web services, security?
