Preventing timeout when connecting to a URL

Question

I want to see the time taken to access a url using Benchmark in the code below. I also tried to do the same thing without benchmark. That is, get time at start of test and end of test, subtract the two to get the time. Both methods end in the same timeout error.

require 'open-uri'
require 'benchmark'

response = nil
puts "opening website with benchmark..."
puts Benchmark.measure{
  response = open('http://mywebsite.com')
}

puts "Done !"
status = response.status
puts status

Error:

opening website with benchmark...

When I try to connect to this URL in my browser, it takes about 2-3 minutes to access, all the time.

I searched google, but found no useful answers to my problem. I know that I have to change the timeout setting for something, but not able to figure out which one. Can someone please help ?

Use the :read_timeout option, specified in seconds, e.g.,

open('foo.com', :read_timeout => 10)
