Not sure what kind of freak
experiment you are working with to achieve .6 ms... do you mean .6 secs???
It's actually an application we have in production. Not really freaky.
I fired off 100 requests to a program that fetched 300 records using RPG
CHAIN operations and returned them to the browser. Total CPU time consumed
is 61 milliseconds, including time in 2 HTTP server Jobs plus 1 other Job
that runs the application code. I'm using WRKJOB option 3 to measure CPU
time consumed. Time includes parsing requests and generating formatted
output, plus inter-process communications.
Since you mentioned round-trip time measured in Postman, perhaps I should
clarify that I'm only accounting for IBM i CPU time, measured by WRKJOB
option 3. I'm not measuring Internet latency.
I put effort into writing applications and web interfaces that perform
well. But it's not rocket science.
