Site takes forever to generate

[zzak]

Maybe because of the size of the site, or we're doing something wrong.. but the site takes around 2 minutes to generate on my laptop; and has made previewing changes a nightmare:

~/code/www.ruby-lang.org => time be rake generate
Configuration file: /Users/zzak/code/www.ruby-lang.org/_config.yml
Building site: /Users/zzak/code/www.ruby-lang.org -> /Users/zzak/code/www.ruby-lang.org/_site
