Rails Performance Analyzers

What are the preferred plugins for monitoring and analyzing the performance of a Rails application? I am looking for both database / query analyzers and the rest of the stack, if possible, although not necessarily in one plugin. Which ones do you recommend? (Bonus points for free :)

For example, this one looks like spify.

RAWK I regularly received performance reports by email. It works by analyzing rail production logs and is always good for me.

I recently learned about Scout from my article on rail monitoring , but I haven’t yet had the opportunity to try it out, it looks promising!

+1 for a new relic.

We’ll also look at five runs, I didn’t play with it, but it seems to have loopback mode for development mode, in the new relic creation mode

Derek here from Scout - we added the Rails toolkit as a plugin. This means that you will get a breakdown of where the query time is spent (db, rendering, etc.), as well as optimization suggestions for slow MySQL queries.

You can play with instruments on our free plan.
