My experience with commercial load-testing apps is that they are
outrageously expensive, a pain to program, don't really scale all that
well, and mostly have to run on Windows with someone sitting at the
mouse. There are some that work better than others, but the free stuff

Anyone know of good guides or general info on
performance testing and emulating real use of
an application.
I would like to understand how to identify
potential bottlenecks before I deploy web apps.

Another application (commercial) is Mercury Interactive's LoadRunner. It
actually records events and plays it back on load generator machines.
It's fairly complex, has LOTs of knobs to turn and can load test quite a
bit more than just web apps, I use it to load test/benchmark Oracle 11i
