RSpec Performance

Rails
1

I’m a windowx xp user and a simples “rake spec” consisting of 1 spec
with 1 exaple takes about 3-4 seconds to run on a Intel Q6600 with
almost no load.

Is this right? Is there a way to make it faster?

Every screencast that I watch when people try the same stuff on a Mac
it runs in 4-6 miliseconds. I know that apple computers are better and
stuff, but what’s the reason for such a big diference in performance?

I know this doesn’t help you, but on my XP laptop it would take 5-10
seconds to create a new app with the Rails command. When I go my
Macbook it takes about 1 second. The Windows machine had more GHz and
RAM, too.

Well, I didn’t find and explanation yet.
I’ll try and profile the spec task to see what’s slowing things down.
I’ll post back if I find anything.

Please also post to the rspec tracker (http://rspec.lighthouseapp.com)
if you do.

On my four year old ThinkPad (T41) w/ 1600MHz Pentium M, 77 RSpec
examples run
in 3.6sec including load time using “script/spec spec”. It is running
SuSE
Linux. Once loaded the examples run in under 2 seconds. “rake spec”
takes
approximately twice as long.

Can you make sure that ruby is in your path early on in Windows? I use
InstantRails and it has a command called use_ruby.cmd that sets the path
to Ruby in its directory. That makes Rails and Ruby respond a lot
faster.

The ruby/bin directory is the first one in my PATH entry. That is not
the problem =/
