Very slow compilation of SCSS scripts

[pawelpabich]

Hi,

I have a bundle transform written using SassaAndCoffee. Initially it worked great but now it takes 42s to process 500 lines of SCSS code. I did a bit of profiling and it looks like most of the time is spent in Ruby code so I don't know if there is anything that can be done about it.
Results:
Run1 :42s
Run2: 23s
Run3: 22s

I'm more than happy to help but need some hints to get started.
Test app can be downloaded from here: http://dl.dropbox.com/u/7579883/SassPerfTest.zip

Thanks

Pawel

I just complied the scripts with ruby gem "scss" and it finished under 3s. Is IronRuby simply slow?

Thanks for providing the sample project.

IronRuby is slower than Ruby for sure, but perhaps there's something that can be done to improve SassAndCoffee's use of it. Is it ok for me to include your Sass files as part of a benchmark/test-suite in the SassAndCoffee project?

[pawelpabich]

Yes

Has anything been done about this? I'm having to dump sassandcoffee in favour of something else because it's taking several minutes for asp.net's first page load. (It's much quicker if I use a precompiled css file).

Same problem here - sass files compilation is terribly slow server side with IronRuby - and now IronRoby get's stuck in some weird loop making SassAndCoffe a non option :(
