The Freeze was probably do to the initialization overhead of starting 32 more instances plus 500 test jobs. Change the test jobs to send a transaction every so many seconds for a few iterations. Have them all start and then delay till a set time, then start firing at the server. This should give you better server performance testing. Also a 720 with only 1 gig of memory is probably paging like mad to handle that many jobs. I would go to 4 gig of memory when the budget allows.

Subject: More AS/400 Web server Load Testing Results
Anyway, with 100 hits at once the HTTP server started 6 more instance jobs
and the average response time was 2.1222 seconds.
With 500 hits, the HTTP server started 32 more instance jobs and the average
response time was 10.629 seconds. On this one the machine did seem to
"freeze" for a few seconds most likely from running that many jobs at once.
