I've been trying to load test our AS/400 web server. It's very unscientific but any results are interesting to me, as I'm sure to others. I'm using the same box to send the requests as I am to produce the results, just an FYI. I am finding that running 500 interactive jobs at once takes more CPU that the web server tryingn to process them. I sumbit all jobs to make there requests to a QSYSNOMAX. I have a program that simulates getting hits from any number of concurrent users on the system and records the beginning and ending times from request to end of response. This last test I did requesting a CGI program that returns XML tax information (using vertex to figure taxes). 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. The web server didn't seem to flinch. If I could make requests from another box I'm sure that the times would improve dramatically. If anyone has worked with Tax software you know that there is a bit of processing involved. We pass in taxable amount, city, state, zip and it returns a few parms, like tax, state tax, etc. My program then builds XML with this data (eRPG program).
