Portal performance

[#1]

Hi folks,

i do have several customers that have performance problems with their enterprise portal.

But these problems don´t have to be "real" problems with the portal itself. It is also possible that they are based in connection to the backend system, they can be network problems, slow database(s), the j2ee engine etc...

Do you know a tool or a process that will enable people like me to find the real problem systematically? Do you have an idea what to test first, have a look at what kind of logs to get some information about the performace bottlenecks?

The best case would be a unified process that will check all possible bottlenecks systematically (does not have to be automated) and help the guy doing the measurement in finding the solution. Is there anybody who already has a solution for this problem?!

I hope you can help me

Kind regards

Hi Micheal

I would like to add some more points:

1. First and foremost, identify the customer scenarios for which the performance is poor and get a clear idea about these sceanrios and make sure that these performance problems are reproducible or repetitive. As rightly pointed out by Joerg, working on all the scenarios will eat up time and money.

2. Get some statistical data such as the %CPU utilization, Memory utilization on different servers (WebAS, R/3 Backend, Databases etc.)from the customer's productive systems, if possible so that the issue could be identified as response time or memory etc. This data will be very helpful to foucs on the right component.

3. Try to have an environment (dedicated and controlled) where the customer scenarios could be simulatedwith differnt monitors enabled so as to identify the exact bottleneck.

Hope this is helpful.

Thanks and Regards
