The Holy Grail of most computer users today is speed - mainly speed on the Internet. I suspect many people would happily sacrifice a great deal if they could save time downloading Web pages.
This attitude has a lot of companies trying to think of ways to speed up the Internet with various software tricks, the most common being some form of cache memory.
Most computers use some form of cache whenever there is I/O. The most common caches are for hard disks, graphics and CPU instructions. The idea is that if the computer can grab what it needs beforehand and pop it into memory, it can be obtained quickly later.
Many products claim to speed up browsing time, but all must be viewed with caution. SurfExpress is one that seems to live up to what it says.
SurfExpress from Connectix (the makers of RAMDoubler and DiskDoubler, as well as Virtual PC) claims to speed up the process of returning to pages you have visited. It is important to understand it will not speed up access to new pages.
The idea is quite clever. Most of us go back to the same page many times out of habit - it might be a search engine page, for example. By caching these pages and examining them against their present date and time stamp, SurfExpress can regulate the 'new' information that needs to be downloaded.
