Show HN: Today's Added .COM names - Instant search on Heroku

HN,

I put my new creation up this morning and now it's on the front of ReadWriteWeb - http://www.readwriteweb.com/start/2010/12/addeddomainscom---....

Thanks to the magic of Heroku I'm now running 11 dynos and serving up to 100 requests per second. Beyond the awesome scalability, Heroku is fast! It turns around requests generally in under 100ms with max 150ms.

Things I learned:

Instant search is hard to scale. A normal user can type 5 characters per second and each character is a full round trip to the server.

Sinatra is fast. This is my first time using it for a live site and I've been very happy with this.

Google has nice fonts on their servers: http://code.google.com/webfonts The font I chose seems to work with nearly all browsers and since Google is serving the font file off their servers, it loads very quickly.

I'd appreciate any feedback that you all have. The site is so in flux that I put it live at midnight last night and then rewrote half the javascript in the early morning hours.

Thank you,

Robert
