No DRb server is running. Running in local process instead ...(Rails 4/Zeus/guard/rspec 3)

I have just switched from using Spork with Guard to using Zeus

I used this step by step guide: http://blog.blenderbox.com/2014/04/10/testing-rails-3-with-guard-and-zeus/

The thing, is now my routine is

• in a terminal window do $ zeus start

• in another terminal window: guard

• in another window : $rspec

My tests are working fine but I'm very surprised that rspec test suite has gotten slower than with Spork as most people say it's a huge boost in test speed.

What also makes me really think there's a bug is that when I type rspec, it displays a message reading what's below before running tests:

No DRb server is running. Running in local process instead

Somebody got an idea what's the problem ?

thanks

You may have the --drb option set in your .rspec file. Delete that line.
