I also took the books advice on changing my ssh port, but had to use google to find the ssh_options[:port] thing.

First off, the books definitely worth getting. I’ve got several young rails apps in production and am hoping to keep them moving snappily, taking Ezra’s advice.

1) Benchmarking performance.
I built an almost-empty rails app and ran ab -n 1000 <URL> against it. The results were frighteningly bad … roughly 27 requests per second. I was about to file a ticket with my hosting provider when I realized I’d started up the emtpy rails app in development. Switch to production and I’m up above 200 requests per sec. A happy moment.

2) Setting up SSH.
I switched my SSH port from 22 (default) to a higher number.
This required a change to my capistrano deploy.rb scripts.

ssh_options[:port] = '<port-number>'

This should probably be noted in the book.

3) Also regarding SSH…
Following the book’s advice, I disallowed root logins on the server. Several of my capistrano scripts – notably, grabbing a mysqldump and importing it into the dev db – had to be tweaked to use sudo.
