Hello,
I have tried with your link and 200 instances took 10 seconds with single thread using normal XMLHTTP library.
I would recommend using this method (and not a faster one) as the website constantly throws an error because data is collected too fast:
{"Response":"Error","Message":"Rate limit excedeed!","Type":99,"Aggregated":false,"Data":[],"YourCalls":{"hour":{"Histo":452},"minute":{"Histo":301},"second":{"Histo":10}},"MaxLimits":{"Hour":8000,"Minute":300,"Second":15}}
I can put a "try again" code if the first try fails.
If you are interested please open a chat with me.
Kind regards,
Sorin
