Re: Ajax enabled pages are slow to load
Thanks Igor for making me THINK! This was my issue. I instituted my own ConfigurationType. At the time I did not realize that the WebApplication.getConfigurationType() was being called at many points during the rendering phase. So each time this method was called it was thrashing about in LDAP - which is where I am storing many of my properties. It makes sense to me NOW :) All fixed and AJAX is working SUPER FAST. --Tim On Thu, Jun 18, 2009 at 11:43 AM, Igor Vaynberg wrote: > seems quiet strange. wicket does not spawn threads - but your ajax > calls do. so the question is what is spawning the threads before the > page renders? > > -igor > > On Thu, Jun 18, 2009 at 6:55 AM, Ames, Tim wrote: > > I have recently converted a project from 1.3.5 to 1.4.rc-4.

Re: Ajax enabled pages are slow to load
seems quiet strange. wicket does not spawn threads - but your ajax calls do. so the question is what is spawning the threads before the page renders? -igor On Thu, Jun 18, 2009 at 6:55 AM, Ames, Tim wrote: > I have recently converted a project from 1.3.5 to 1.4.rc-4.

Ajax enabled pages are slow to load
I have recently converted a project from 1.3.5 to 1.4.rc-4. The only thing that I have changed with it is adding all the generics. On pages, panels, etc. that I have ajax classes, the pages are taking a great deal of time to load. They were not exactly quick to load for me in 1.3.5, but in 1.4.rc-4 they are painfully slow. While in debug mode, I check during the database loading phase and all that is running very quickly. It seems to be at the rendering phase where the problem lies. I notice in the stack that there are many many Daemon threads being created before the page will finally display. I have ran this in development and in deployment mode with no appreciable difference (and on two different web servers). For a test I placed a breakpoint in the onRender() method of the page. The breakpoint occurred about halfway through all the Daemon threads that were being created. I am using Tomcat 6.0.14 I am noticing this in other projects not just this one. Any suggestions on what to look for to speed it up? I do have logging on with info, so I have verified that all the objects are serializable. One of the projects has a webpage class with a mix of these ajax components: AjaxSelfUpdatingTimerBehavior; AjaxLink; ModalWindow; IndicatingAjaxLink; Timothy Ames Developer II Promedica Health Systems, North Direct phone: 517-265-0281 Internal extension: 72281 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ EMAIL CONFIDENTIALITY NOTICE This Email message, and any attachments, may contain confidential patient health information that is legally protected.
