Rails performance issues

[Paul Michael]

I read a blog before from a Twitter developer saying that they encountered performance issues with Rails and had to perform some hacks just to make it scale. While making those hacks they lost some of the benefits of having to write the application in Ruby.

Is performance still an issue with Rails? Would you rather recommend developing in PHP (Zend) or Python (Django) instead of Ruby on Rails?

Thanks.

According to http://highscalability.com/scaling-twitter-making-twitter-10000-percent-faster Ruby on Rails is not to blame for Twitter's performance problems.

Don't believe everything you read on TechCrunch :-)

They're still using RoR for the site, so do many other high profile sites. The key to that, Rails keeps moving forward, it came a long way since 1.0, the upcoming 2.3 is much faster, better caching support, smarter queries, etc. I think Rails got to be good enough for general purpose sites around 2.1.

The scaling strategy for RoR is the same as PHP and Python, and I recommend you check out the [url=http://railslab.newrelic.com/scaling-rails]Scaling Rails videos[/url].

That's re-assuring to know. I was thinking of making an investment on studying Rails.

Thanks for your replies, Assaf and Orjan!
