The previous one (back in 2008) was indeed against the Access DB, and now I'd like to find out how Oxle (being on SQL) can handle such loads. However, the test has already ended, and we didn't get more than 28 concurrent users online at any given time.
I'll have to find a way to get more people from all over the world to participate at the same time....going to get out my thinking cap and come up with a cunning plan.
You mentioned the contest ... ask for interested parties to contact you (so you know how many to expect) ... set a date and time (to get them all there at the same time) ... create a place for them to meet (like you did the first time), write up a post explaining the details of the contest and provide some reading material introducing the Q.Oxle account and why it is übercool (to give folks something to do while the test is being conducted) [perhaps even a tour of some übercool public accounts] ... maybe provide them a quiz to take to test their comprehension of the stress test and the Q.Oxle offer (again something to keep them entertained during the test) ... remember to send out a thank you to all of the contestants.
