Hello,

I’m trying the new I18n feature that will be included in Rails 2.2

But I have a doubt running in my head:

What’s faster(better, more performance)?:

1. Put a I18n.load\_translations in an initializer that loads all  
available locales when the server starts.
2. Put a I18n.load\_translations in the ApplicationController that loads  
only the locale proper to the current request.

I hope I was clear… :S

Regards, and thanks in advance.

If you’ve got the RAM then #1 will be faster for sure. I’d recommend it,  
since RAM is cheap anyway.
