Upgrading to newer versions probably isn't going to help you. The latest code will typically cache the interface statistics for several seconds, rather than re-reading them afresh every time. Such versions will probably handle a rapid rate of queries better than earlier ones, but you'll get the same answers each time (which rather negates the point!) There's always a balance between timeliness of the information and the cost of retrieving this information. For most modules other than the most straightforward, I doubt whether a sub-second query rate is realistic.
