By default mod_rails does “ok” cacheing of static files.

For example for each page the browser will request “has this static file changed?” from apache, apache will say no, and there won’t be a huge slowdown, but there is still some slowdown.

To avoid it, set your static content to never expire (since it doesn’t need to because of the ?timestamp that rails already affixes).
