Thanks for your answer!

I think the PHP warnings are because I have disabled them, but think it 
would be a good practice to turn them on again haha.

As you could have seen, in my PHP script, the cURL handle is not closed, 
what improves a lot the request speed as I have tested. May be because 
of this the Ruby script is slower.

So the "slowness" of the script is because of how connections are 
handled I guess.
