Cobweb gem causes Rails app to run 10x slower

Whatever it was, I seem to have fixed it by deleting the Gem and reinstalling it. Deleted it using JosephL's advice here:

I take it back. This is still an issue. When the gem is properly reinstalled the web server speed drops from 2s to 50s.

Same if you force Webrick. Same if you use heroku local. I don't know what the gem is doing on initialization - I can't figure out why this should happen.

But it does.

Another datapoint. If you add the gems that cobweb depends on to the main application Gemfile, there's no problem. It's only when cobweb itself is added.

Thanks Simon,

Cant think off hand what it could be, i'll take a look later and see if i find anything, on a train just now.

had a quick look on the phone, first a couple questions... is it always the same amount of time delay? there are a couple monkey patch bits of code that should be considered. Also do you have a gemfile you are using (and lock) that i can plug into a test rails app, oh and version of rails too. There is a require that loads all rb files that are in the same or sub folders from lib/cobweb.rb, if its missbehaving, could be related.
Nothing obvious though, if you can send the above i'll het a test app running to try to replicate. Also, what version of cobweb your on too.

thanks,
Stewart.

Thanks, after a bit of wrestling with recent el capitan update, i've been able to get rails installed and can replicate this locally with the rubygems gem. I'm going to now try to replicate with local copy and see what its up to.

[stewartmckee]

Ok, think i've found it, try version 1.0.29.

Evil, Evil, Evil monkey patching on the String class with method_missing....

Glad its working now.

thanks,
Stewart.
