Phusion Passenger (mod_rails): finally a good Apache module

Head over to modrails.com and you’ll be greeted with a screencast of how fast and easily you can set up mod_rails. I’ve always hated the idea of having to run a cluster of mongrels for each rails application I want to deploy. It’s also prohibited on most hosts due to a need to manage the mongrel processes and the memory consumption of each process.

With this we can now load up only what we need when we need it, using the same Apache for all deployments. (Unlike with mod_ruby.)

Now, this is only for Rails and Hongli Lai talks about why this is in his blog post, Passenger and other Ruby Frameworks.

It’s not yet available, which I’m still failing to understand why, but when it is I’ll be quick to install and play around with it.

    It’s because we want the first release to be perfectly stable. :) We do not intend on releasing a half-assed may-or-may-not-work product. You can expect a quality release.

  2. Fair enough! I am, as I’m sure a lot of people are, itching to get our hands on it! Any chance we’ll see some performance/memory usage numbers before the official release?

  3. I’m not sure, we’re working around the clock just to get this thing released. Benchmark numbers may be released at the same time or after the public release. But according to the benchmarks we’ve done so far, performance is on par with Mongrel behind mod_proxy.

  4. I’d be interested to see how it affects Apache’s memory footprint.

  5. Hi kritikal. Sorry for spamming, but I thought this might interest you. Passenger has been released as of today. :) You know where to find it. I don’t put an URL in this comment, in fear of your spam filter. ;)
