Re[2]: Long time processing in the DwrServlet.service()

Greetings, Mike

MW> There have been some small changes to thread wake-up for 2.0.4 so you

MW> https://dwr.dev.java.net/servlets/ProjectDocumentList?folderID=9081
Ok. I will try it in the 2nd stage after applying all other your
suggestions. To be sure that something is changed. :)

>> StatisticManager.addValue(request.getPath(), duration);

MW> Nice explanation of your tests, and yes they make sense I think.
MW> Use  request.getPathInfo() instead of getPath() in your next
MW> deploy as this is the value that DWR bases its decisions on. Just
MW> to be sure. (See UrlProcessor.handle)
There is no equest.getPathInfo() in simple. And it returns in the
Adaptor between simple and servlet APIs.

Hm.. I will check the req.getPathInfo();
Thanks

Unfortunately, I can't use Wireshark on live system. (Too many
restrictions for debugging :(( )

MW> You could also make your JavaScript code count the number of

Ok, yes. it should give us new information. I will add the counter to the
JavaScript and counter of request with duration more than 30 sec and
will compare them.

Thanks for your suggestions. I will try to apply all of these step by
step and will let you know about the result.
