For ruby apps I suggest you to use thin or mongrel both are fast and doesn't use fork like Passenger do.

Really I've no experience with go/python/php but for best comparison you should check:

• Number of threads that the webserver can fireup
• Threaded or Forked for handle concurrency

Thank you! Great job!

Thanks for your input. Could you be a little more specific about what you are suggesting?

I chose Passenger because I figured Apache would be a good baseline for everything (mod_php for the PHP tests, mod_wsgi for the Python tests, mod_passenger for the Ruby tests). Sure, the Go test doesn't fall into this category but I kind of consider that a different animal.

Yep, passenger is a awesome webserver/module, but (I think) other than mod_php and mod_wsgi to handle concurrency request like an ab test can do it fork the ruby process for each request.

This a great workaround to scale but isn't the best way to track performances, no?

You want to track how many concurrency request can handle 1 ruby process?

If so, there is a great feature in passenger.

See here

In particular I suggest some like:

PassengerMaxPoolSize 1
PassengerMinInstances 1
PassengerMaxInstancesPerApp 1
