Supportpac WP01 explains how to calculate BWU. I'm not really in the mood to create the workflow and client applications myself. Is there a place where I can download the fdl and the client application?
Thank you

What do you really need? I am confused.

Francois,
If I am not mistaken about your question, what you seem to want is the ability to perform a BWU calculation on an FDL that you would like to have handy without creating it yourself....?
If so, workflow usually comes with a standard set of fdl's such as "fmcred.fdl" etc etc. Do a search on your machine, get a good sized fdl, import it into buildtime or modeler if that's what you are using and check to see if there's a good level of nesting. Now perform the BWU calculations using the available support pac.
Hope this helps, and good luck.

No, the supportpac describes a method of building a workflow with 100 nodes etc., this way you can set your own benchmark for your own unique setup. I was wondering if anybody buildt that workflow.
The section in the supportpac is: "Measuring the BWU capacity of a system"

I've calculated the BWU capacity numerous times and you do not necessarily need to use the exact configuration as IBM describes in the support pack. In fact I prefer not use use such a configuration because it does not include manual activities, blocks, transfers on container elements which may be significant factors to overall performance. If your goal is to see how your hardware stacks up to the standard BWU test because IBM has not performed a benchmark for it, then you can download a process model that is similar to IBM benchmark test but it uses No-Op activities instead of activities that actually start an activity.

If you are really looking to see how your machine will perform in production, then the standard BWU test isn't very realistic. The simplest approach is to analyze all your process templates and create a single process template that represents an average process template with regard to number of manual activites, automated activities, block interations, and container elements. Then create simulation software that will interact with this average process template to mimick various expected load levels. I've done it a few times with very accurate results when compared to the production system once installed.
