Memory Management and cache usage

With Vista, Microsoft introduced a new technology called Super Fetch for caching applications and
speeding up boot times. This feature preloads frequently used applications into RAM, so they can be
accessed quicker when they’re needed.

The Super Fetch feature in Windows 7 differs significantly in approach and cache memory usage from its
counterpart in Vista. Under Vista, the caching of applications starts immediately at boot-up. In
Wi9ndows 7 Super Fetch gets a delayed start and eventually also allocates much lesser RAM to it. This
means Windows 7 uses lesser resources without affecting performance and launch time of applications.
The cache usage is also lower as compared to Vista.



Networking

Windows Vista had promised optimized TCP/IP, but didn’t live up to the hype. There were new features
like option to set up ad hoc Vi-Fi networks using the network Setup wizard, WPA2 encryption,
remembering settings for different LAN connections and the Network Map displaying a graphical view of
all your network connected devices, but internally it was no major improvement over XP and file
transfer speeds were even lesser than XP generally. No amount of user friendliness can mask the
difference in speed. Windows 7 takes Vista’s plethora of features and adds Home Groups. But that’s not
it, the performance difference is noticeable. Transferring large files is significantly faster than even XP.
The option of setting up a Home Group, which although limited with other Windows 7 machines, make
networking simpler and managing a home server easier. Troubleshooting solves most basic problems
without requiring any input from your part and you don’t have to call tech support over minor problems
like IP conflict and a disabled DHCP.
