> We're doing performance analysis and looking for bottlenecks ... In that case, you want to test a single server only, at least to start. You'll need to define user paths that are most likely to be followed by users within the application, and define timers for each step of the user path (where a step is a single user action that triggers any server-side response). Then, you'll run a typical performance analysis test (no pauses between requests) for a single user, then scale up by some increment (say, 5 users) until the application becomes unresponsive. The data you collect during this process will primarily be response time data (for each timer). You can then drop that data into a spreadsheet and chart the timer steps that increase more than others, and those are your bottlenecks. If those steps are themselves pretty complex, you can add CFTIMER tags within your page to find out which part of the page is the slower part, as well.

Well, that might require a different test, or at least might affect the point at which the application becomes unresponsive as described above. Proper performance analysis testing can really only happen once you've removed functionality and operation bugs from your application, and memory leaks would fall into that category. That said, it's unlikely you'll run into true memory leaks with CF components - you just might run out of memory, though.
