Rails generate tool takes about 20 seconds to start for any action

Rails
1

When I run “rails generate -h” it takes a little more than 20 seconds to
print anything, the other tools, like controller, model, scaffolding,
migrations, etc, too.

While the code is executing it uses 100% of CPU (well, actually 50%
because it’s dual core)

Any idea why this is happening? Since I’m really new with rails I tend
to try all options and with this I’ll be like the whole day =/

Please provide more information about your environment, OS, version of
Ruby, version of Rails, etc.

Also the specs of your computer, CPU, amount of memory, HDD size and
free capacity, etc.

The more information you provide, the better we will be able to help
you.

OS: Windows 7
Ruby: 1.9.2
Rails: 3.1 RC
CPU: Intel Code 2 duo 2.4Ghz
HD partition: 60/112gb

The problem is that it even takes 20 seconds to show the help command,
==the help command== “rails generate -h” 20 seconds to execute

Ruby 1.9.2-p0 up to 1.9.2-p290 (recently released) really suffer from
performance issues on Windows.

Ruby 1.8.7 on the other hand, is way more faster in this area.

Ruby 1.9.3, going to be released next month improves performance on
Windows, but still is not as fast as Linux (even so, way faster than
what you are describing).

If you’re not forced to use Ruby 1.9.2 for a particular reason, I
would recommend downgrade to Ruby 1.8.7 until 1.9.3 gets released.

Woah, I didn’t know it was so bad the issue, well, I’ve everything
installed and working already I think I’ll go for waiting for the next
version, since most tasks work just fine, Rails runs flawlessly, except
for the generation script. Thanks for the information and suggestions ^^
