Personally I've had a lot more success using DTrace to profile Rails apps. You can even attach to an existing process, so you can trace Passenger servers. You need to be running Mac OS X (Solaris may work too, but I don't know) but most Rails devs do so...
You can find an example script on here: http://github.com/andyjeffries/rails-analysis-tools (look at the Passenger DTrace script section of the readme) Cheers, Andy -- Andy Jeffries http://andyjeffries.co.uk/ #rubyonrails #mysql #jquery Registered address: 64 Sish Lane, Stevenage, Herts, SG1 3LS Company number: 5452840 On 24 February 2010 11:59, Tom Mac <[email protected]> wrote: > Hi > I am asking related to this.
