Ricardo has rewritten the Heroku toolbar, porting it from a Rails
monkeypatch + Mongrel gemplugin to Rack middleware. The benefits that
you guys will see are:
- All apps are now running on Thin, which gives a bit of a speed boost
over Mongrel.
- Toolbar is way faster to load: less static assets, less rendering time.
- No more heroku_marker problems. (We removed the rarely-used Inspect
button; it may return in an updated form in the future.)
- No prototype.js or other javascript library to load, so no conflicts
with JQuery or Dojo.
I'm most excited about the first two points. Combined with a bunch of
other optimizations we've done recently (esp. in regards to static
assets), Heroku apps should be serving substantially faster now than
they were a few months ago.
Three cheers for Ricardo! :)
