Hi @ all  
Can somebody explain me, how can I measure the latency of my network  
with a ruby app? Does in the internet exist any websites about network  
theme?

thanks for your solution!

The easiest thing would probably be to use the net-ping library and ping  
the  
other network device and then look at the response time:

irb(main):001:0\> require ‘net/ping’  
=\> true  
irb(main):002:0\> p = Net::Ping::External.new(“72.14.207.99”)  
=\> #\<Net::Ping::External:0xb7c544e0 @port=7, @duration=nil,  
@warning=nil,  
@timeout=5, @exception=nil, @host=“72.14.207.99”\>  
irb(main):003:0\> p.ping  
=\> true  
irb(main):004:0\> p.duration  
=\> 0.088548  
irb(main):005:0\> exit

I’m not sure I understand the second question.

HTH,
