Try a personal copy of
Spb Benchmark. It's not 100% made for the Touch Pro, but works well enough. Since the Touch Pro uses Opera Mobile instead of Pocket IE as the default browser, you might want to exclude the Internet Explorer tests, because you'll get errors. Also,
someone I learned about it from said it's best to disable the Pocket Word benchmark, but they were testing a Treo 800w. That thread contains some results for various devices if you want to look at some values to compare with.
