I agree with aliasmaximus. However, over the years I've seen most of the complaints of slow loading to be locale specific and transient. Right now, sitting in in rural western MT with a DSL speed maxed at 13.1 Mbps my GT lesson pages are loading nearly instantaneously.
Check your settings and/or talk to your internet provider. Most likely your problems could be your system, your location or your provider.
But, I've been wrong before. 😁
