All performance benchmarks are included in the distribution -- please try out for yourself, the file bench/README.txt has some additional details for how to run each benchmark.
about the benchmarked systems
Qpy is a templating system almost identical to straight python and offering convenient and fast (at least the C based version) html string building with automatic escaping. From the Qpy readme: Qpy provides a convenient mechanism for generating safely-quoted html text from python code. It does this by implementing a quoted-no-more string data type and a modification of the python compiler.
The performance of Evoque and Mako (comparable text-based systems) seems to be more or less similar -- Evoque seems to be faster for general mixed-task templates, while Mako seems to do better on loop-intensive templates.
Suggestions to make these benchmarks more relevant are welcome, especially from anyone with particular knowledge of the specific templating system in question.
The actual times are coming off a MacBook Pro with 2.4 GHz Intel Core 2 Duo, 2 GB of RAM, and Mac OS X 10.5, running Python 2.6.1.
Please remember that performance benchmarks are only relevant when considered within an entire context, and they may vary enormously between different combinations of hardware and software, even if those difference may appear to be very slight. In addition, two different systems never quite do precisely the same thing, however simple and apparently identical the timed task may be.
The numbers from these benchmarks are a tribute to python's conceptual integrity -- that rewards a straightforward implementation of a simple design with... amazing performance.
