Superfetch is interesting in theory, but is not neccessary. Thisshould be an option to turn on if desired. Superfetch leaves nomemory for using other programs, especially for gamers. I can see fora business setting, this would be great, if someone does the exactsame thing at the exact same time on their computer every day. Howoften does this happen though?? pretty much NEVER! Another bad thingabout superfetch is that it seems to work with microsoft productsonly. Not once have I noticed any performance increase from haivingthis enabled. In fact, I have always had a decrease in performancewhile having it enabled. This service should be removed or disabled,and MAYBE be given the option of enabling it for a businessenvironment. I currently am in charge of quality and assurance in theUS for a global software company, and I test our software on severalwindows platforms. This software requires a lot of system resources,which are not available if superfetch is enabled. This works the samefor any other non-microsoft product. I spend plenty of my time"tweaking" windows and its services to have the best performance.Superfetch is by far the worst of them all. Anyone who doesn'tbelieve this.. just try stopping, disabling superfetch, then restartyour computer. You will notice your cache will be free, and you willhave much more free memory to actually use other programs.
