Could you add it to the merb.yml (commented out like the other various options) so that people know about it in future releases?

Thanks for writing this nice post on Merb! Did you turn off locking? By default, Merb will lock through the controller code, serializing that portion of the requests. This is required for ActiveRecord code to behave, as AR is not thread safe. The Merb responses are quicker because it's threaded up to that point, whereas Rails locks for *everything*. If you add: :use_mutex: false in merb.yml You'll get better results yet. :-) Hello Mike. Thanks for writing this nice post on Merb!

By default, Merb will lock through the controller code, serializing that portion of the requests. This is required for ActiveRecord code to behave, as AR is not thread safe.

The Merb responses are quicker because it’s threaded up to that point, whereas Rails locks for *everything*.

If you add:

:use_mutex: false

in merb.yml

You’ll get better results yet. :-)
