HI Austen,
If you want to get data faster, this is possible, but I would suggest you don't use "GetValues" for this.. Instead I would suggest that you use the built in Subscription mechanism in EWS.
Subscriptions basically allows for you to specify a list of IDs that you want to watch (with a Subscribe request), and when you send a GetNotification request, only the values that have changed since the last time a GetNotification will be returned. (Also there is Renew and Unsubscribe requests.) From a performance perspective, SBO is much better and it is the recommended approach. In the case of SBO as the EWS Server.. You could definitely ask for data more often doing this, I have done it every 5 seconds with no problems.
In Mongoose.Processor.Ews there is a class called "SubscriptionReader'. It is there to help you facilitate this, all you need to do is pass in either a list of items, or a subscription Id, and it will handle the EWS requests it needs to send for you, including handling the Renews if needed. It will also notify if your subscription id changed (due to failures).
I have attached the GraphicsUpdateProcessor (From Cerberus). Which shows an example of the Subscription reader being used for new subscriptions (SubscribeAndReadNew()) and existing subscriptions (ReadExistingSubscription()). Again, note this is proof of concept code, so it is just to be used as an example.. I wouldn't copy and paste
