Tonight I came up with an idea which actually works so well, that I would like to ask some people who like to fiddle with windows to give it a try and share your expierences.
What you need:
A fast PC and internet connection and enough physical RAM to spare, say anything higher then 8 Gb. In this example I'll use my own setup:
i7, 12 Gb RAM, 50 Mbps internet connection.
1) Create a virtual RAMdisc using this freeware of at least 1 Gb. This will be a closed block in your physcial RAM that's permanently in use and is made into a drive.
2) Redirect your browser cache to this RAM drive.
3) Enjoy your new superfast cached internet. Sites (provided that they are hosted on a fast server) open almost instantaneously. It's ridiculous how well this works.
