Multiple API calls at once?

I've put together a trading program that works fairly well, except when I call the API for each currency, I have to do each currency in order consecutively. Because the API from the site is slow to retreive the info, I am missing a lot of trades in the time it takes to get all of the rates. Is there a way to speed this up by getting all of the rates at one time somehow?

The site is www.cryptsy.com. The API info is here: https://www.cryptsy.com/pages/api

Any ideas?
