Hi all,

I want to know ,what factors are involved in checking the performance of our code in rails 2.3.5 and above versions?

And also whats the difference between rails 2.3.5 and earlier versions ?

Try googling 'rails performance testing'

And also whats the difference between rails 2.3.5 and earlier versions ?

Try reading the Rails changelogs

Generally speaking, people here won't do your homework for you, figuratively or literally. Do some research on your own, then come back with more focused questions.

Same as with just about any platform, benchmarks and code inspection.

Tools I found useful: newrelic-rpm, ruby-prof, kcachegrind

Are you having performance and/or scaling problems right now? If not then you don't have a performance or scaling problem.

I'd take the 37signals approach and deploy a beta of your application, and attach New Relic (or similar) performance monitoring to it. Then worry about performance or scaling issues when New Relic tells you that you have a problem.

That being said, common sense still applies. A good test suite, benchmarking and thorough code reviews may point out some obvious bottlenecks and misguided implementations.
