Hello, I try to upgrade existing application from rails 3.2 to rails 4.1
Then I change any 1 line in coffee script server hang for about 1 minute
and load CPU for 100%
For exemple I make same change for same page for old code
http://pastebin.com/bpMd0KyS - profile log 54720ms vs 879ms
http://pastebin.com/jicn4awq - Gemfile
I comment gem 'therubyracer', platforms: :ruby so it use nodejs, when
rendering takes 9647ms. It’s still a lot compare to 879ms in rails 3 and
therubyracer.
Where can be a problem?
