Mason - A Template system for us programmers

Templating Modules are a bit like editors. Every web application developer has a favourite one. And every template system is someone's favorite.

Mine is Mason. But not because the Perl MVC tutorials are full of examples using Mason. Not because it's the fastest (use xSlate if you want to trade speed for flexibility). Not because it's the most popular. It's my favourite for a very plain reason: It makes me more productive and allows me to develop web GUIs using all the powerful features a programmer should biterly miss if they are taken away. That includes writing Perl code :P

I never heard of a business that went down because they didn't have fast enough CPUs, so I'm not fussy about trading a few CPU cycles for elegance, ease and speed of development.

Enough talking. Here's my contribution to the template holy war and Mason lobbying presentation:

The only bad thing about Mason

At the moment, I'm writing a presentation about Mason2. The goal is to somehow convince my colleagues to consider using Mason. Instead of Template Toolkit.
As part of it, I thought I'd do a bit of performance benchmarking against Template Toolkit. So I put together a reasonably complex mini set of templates using both systems. Well, as complex as TT can take in reality. Which is not very much.

But anyway, let's jump straight to the bad news.

        Rate Mason    TT
Mason  901/s    --  -51%
TT    1852/s  106%    --

As you can see, with similar settings (code caching enabled) and over 10000 runs of two pages, Mason2 is twice as slow as Template Toolkit. Mason2 is still below the millisecond per page in my benchmark, but still that's quite a big difference.

As the common wisdom goes, CPU time is cheaper than programmer time, so it shouldn't be a big deal, given the huge gains of productivity you should get by using Mason2's very cool and powerful features.

Stay tuned for the full presentation to come!
