Performance benchmarking Python3.4 Coroutines & Golang 1.2.2's goroutines

###Problem

There are 208 web URLs. Write code to get the content length of each of the URLs.

###Constrains

• Use libraries/modules which are native implementations in the language
• Find the language with least CPU,Memory & Threading footprint

###Inference

Before the inference is shared, I would have to state that my understanding of both the languages is relatively less. Hence the comparison might not be apples to apples!

From screen cases below, one could infer:

• Go makes magnitude lesser number of system calls & context switches
• Python 3.4 coroutines not so bad

###ScreenCasts

• Python 3.4 Coroutine Performance
• Go 1.2.2 Goroutine Performance
• JRE 1.7 Java Executor Framework performance
