I have production Websphere Portal running our application created on the "old" WPF 6.1.2
The current production is:
WebSphere Platform 6.0 http://ND 184.108.40.206 cf270815.03 http://WBI 220.127.116.11 o0717.03
Host Operating System is Linux, version 2.4.21-63.ELhugemem
It is running fine.. no issues.
We got the same WAR created on WPF 6.1.2 and tried it in a upgraded Webpshere Portal, running
What happens is that pages are taking more than 1 minute to load, but sometimes it goes pretty fast. And I'm sure it is not related to some DB issue, it looks more a compability issue between WPF 6.1.2 and Portal 7.0
Did someone already get the same issue?

Re: Slowness (more than 1 minute to open page) after PortalServer update - WPF2012-12-06T20:07:45Z in response to SystemAdminI would recommend a couple of actions here. First, I would examine the loading performance of the page using tools like the Chrome debugger, Firebug, dynaTrace, etc. This will show you which requests are taking a long time and whether the time is being spent waiting for the request to be processed at the server or for the client to render.
As a second step, I'd recommend turning on model action tracing in your WPF WAR. The model action trace log will show you which actions that were executed in the WPF application and how long each action took. You can then use this to selectively investigate the poorly performing actions.

Re: Slowness (more than 1 minute to open page) after PortalServer update - WPF2012-12-07T14:14:19Z in response to SystemAdminWPF 6.1.2 does not support Portal 7 so it's not surprising that you've hit some issues. See the following link for the Portal versions supported by the WPF 6.1.2 release. You may be able to get the WAR running as needed, but you won't be able to count on getting support for this configuration if you run into other issues. I'd recommend upgrading to a more recent release of WEF, if possible. As I recall, WPF 6.1.2 goes end-of-life sometime in 2013.
Re: Slowness (more than 1 minute to open page) after PortalServer update - WPF2012-12-10T20:42:10Z in response to DGawronThanks for the help.
I set the model action tracing to DEBUG and found that the REGEN action is taking more than 90seconds first time it loads:
-- TIME: 2012-12-10 13:28:49,481 --
Thread: WebContainer : 1
User Name: xxxxxxx
2 98567 Start Request: WebAppRunner.doRequest
0 0 ListPortlet
164 98240 Instantiate: ListPortlet
97901 97901 .Regen: xxxxxService:Default,xxxxxxListPortletContained:Default,xxxxListPortletConfig:Default
My question is: why it does that only the first time after I restart the portal server? And why it repeats that if I stop working on the portlet for about 1 to 2 hours ?
Do you know if there is some config properties I can change to avoid this?
(not sure if I was not clear, if I run the same page again, the 97seconds goes to 0 second...)
