Suggestions on tuning Hamlbars performance?

[robwierzbowski]

Working on an app with ~30 medium sized hamlbars files, hamlbars takes 26 seconds to compile. We're running it as bundle exec haml -I. -r hamlbars, with Haml 4.x., from the command line.

Is this normal, or is there something we should be looking at/doing better? Our raw haml files are smaller, but proportionally compile much faster.

Although now that I look at the source code I think it might be because it's loading Sprockets/Tilt. Thoughts?
