We are most likely approaching a situation where we will need to
evaluate the possible work load for a given AS/400 machine handling
web services.

One candidate is naturally java since the tools are all there, but the
question is what can be provided with the tools you are familiar
with. Can you elaborate on this?


You want a load tester for your iSeries to see what it can handle as far as web service requests? Or are you looking for something on the iSeries to handle web services (ie accept and/or make requests?)

If you're looking for a load tester, the bottleneck usually lies in the machine making the requests as it's hard to make 1000 simultaneous requests from one machine to load down another (especially if it's a PC)

I've done this in the past a little with two iSeries. I find a bigger more powerful iSeries and submit as many jobs as possible that make web service requests to the other to QSYSNOMAX so all the jobs will run as many at a time as the machine will allow. I record the data from each hit, and make assumptions. :)

If you're looking for something to create/process web services, check out www.rpg-xml.com. Great product, RPG based, no Java or Websphere, and fast.
