Thanks, I downloaded and tried it out and there is absolutely nothing abnormal appearing to happen in any of those areas.
It really looks like the same symptoms you would see if you were running a dial-up connection but I actually have a 120Mbps cable connection and, as I said, it affects every page and all those pages load instantly in every other browser. Any other ideas? Being able to use Google Maps in our app is absolutely crucial but at the moment it is completely unusable.

Double click on your process to see detailed views of thread performance, GPU usages, context switches and so on. See if you can spot some irregularities. On Fri, Jun 19, 2015 at 10:18 AM, John C.
