As far as I understand, the Django app you used has different functionality from Wordpress, so not sure how much this benchmark is useful? How caching is implemented on each app, how much I/O access the URL you benchmark requires (esp. session, which IIRC may fall into race condition in ab-type benchmarks) can make a huge difference (also IIRC - PHP should perform significantly better as Apache module than under FCGI) Ultimately it's really an app comparison, I'd guess PHP or Python have relatively little impact on the results. Find a Django app (or RoR, or even another PHP app) that gives you everything you need from Wordpress, benchmark and you'll have useful data.
