Hello,
Sorry for the late response on this.
I’m afraid there isn’t a way to use it for connecting to The Forge, at this present time. I’m guessing that you’re loading a lot of content that normally is just already available on your PC, and therefore doesn’t have to load, to explain the speed differences.
You you can install a web app of The Forge, which would do similar to what you are trying to accomplish by following this guide here: What is "The Forge: More Awesomeness" module?
If you are experiencing problems in terms of your browser freezing or having significant lag issues, you may want to check out the following guides in order to fix the issues you are having: Fixing World/Performance Slowdowns
