[thelist] load testing tools and concurrency

[John DeStefano]

Thanks, Paul and Peter, for recommending Apache JMeter.  Looks like an  
excellent tool; I've played with it for about an hour now and it seems  
to be able to do all I could ask and much, much more.  If you've  
happened to have used JMeter and come up with a tried-and-true Test  
Plan, please pass it on or send along your suggestions for useful test  
components.

I'd also appreciate your feedback on concurrent requests:

> MySQL + Python + Apache) seems slow with sequential reads, but even  
> worse when concurrent requests are used.  I'm being told that this
