3. Defining Performance Responsiveness Resource utilization
Unresponsive system  Customer dissatisfaction
Resource utilization
CPU, disk, memory, network, battery
Resources are limited and shared
Good Citizenship
It takes one component to impact system performance

4. Windows 7 Performance Enhancements
Performance work started with Windows Vista
I/O Models – Caching – Network Protocols
Startup / Shutdown / Resume
Continued to improve in Windows 7
All of the above...
Superfetch and Readyboost
Device Drivers (Industry / Parallelization)
CPU / Memory Management
Logon time (Redirected folders etc.)
