KM & UWL - Portal performance low

57 Views

Hello,

Can anybody please give us some hints to portal performance tuning using KM and UWL ?

We have the following problem.

We created an application server for our portal. This application

server has 1 dispatcher and 3 server nodes.

For one particular test, we tried to load 900 KM/UWL virtual users on

the system. When we got to around 500 users, the portal application

server practically died.

The script that our virtual users follow goes this way:

1. User logs into the portal.

2. Initial page is loaded. As part of the initial page, the UWL is

collected from three backend systems.

3. User clicks on a link on the menu, which brings up KM. The user

navigates the KM by clicking on hierarchical links, till he gets to the

document.

4. User clicks on the log off button and confirms that he wants to exit.

For the instance we have set the following memory parameters.

MaxHeapSize=2048

-XX:PermSize=512m

-XX:MaxPermSize=512m

-XX:NewSize=341m

-XX:MaxNewSize=341m

Thanks for any hints,

Best Regards,

Volker
