Mako Server's benchmarks are impressive and I'm very curious how they managed to double the page rate of Apache. It's too easy to be a critic...
- dynamic files, depending on complexity, are easier to produce
- mako server is a micro server and therefore does not have all the features or protections that Apache does
I think the biggest difference is the licensing. Mako's prices seem reasonable but they are not free as in beer or anything else. Frankly there are so many other servers out there that are FREE that mako needs to fall off my radar.
