It's a good first swing, but I'd be interested in seeing how it runs with various numbers of clients, and how it runs as the number of clients goes past optimal. I.e. a nice smooth downward trend or a horrible drop-off for whichever drives.
Yeah. I was thinking the same thing..
I need to automate the tests so I can incrementally increase the scaling of the seed tables and increase of number simultaneous clients over time. Put another way,I need to do A LOT more tests that will gently increment all the testable factors one small step at a time.
