+Putting the following in your shell config (eg. `~/.bash_profile`) will make Rails even faster, but will increase its memory footprint. For most applications, this will probably work well for you:
 
     export RUBY_GC_MALLOC_LIMIT=60000000
     export RUBY_FREE_MIN=200000
 
+If you have a particularly large rails app (say, >100k lines), this seems to improve it even more:
+
+    export RUBY_GC_MALLOC_LIMIT=1000000000

 ### More BONUS!
 
 If you're feeling adventurous, you can set some additional compile flags before you run the command above. These may cause the build to fail. If so, you can try again without the `march` flag, and it'll probably work. **This generally makes my ruby ~1.5% faster**. See http://en.gentoo-wiki.com/wiki/Safe_Cflags/Intel for more guidance.
