I am hearing by lots of programmer that Ruby lacks in performance with comparison to php. So i try to find out the real picture behind that i saw this post Why do people say that Ruby is slow? .
There are many articles I found but most of them are too old to be considered for me in current scenario as ruby 2.1 already revealed. As a Ruby on rails developer I loved it. But want to know is this true and if yes how can we overcome this bottleneck in ruby .
So please put your thoughts on that
