Something else I've just noticed - if you have an AV product installed then check its activity when refreshing your GWT app in OOPHM. I have Kaspersky Internet Security installed and it was taking a load of CPU and its memory usage shot up to 300mb during app refreshes. Once I had configured it to completely ignore my developer instance of FireFox, my app refreshes dropped from 16 seconds to 9.
