Ensuring Good Performance Responsiveness Unresponsive system  customer dissatisfaction Resource Utilization CPU, disk, memory, network, Battery Resources are limited and shared by others Good Citizenship It takes just one component to impact the entire system performance

Power Efficiency

Power Efficiency “All day” mobile PC battery life TCO – reduced cost of energy consumption New power consumption regulatory compliance Environmental consortiums for computing (Green Computing) Software performance is critical for Power Efficiency Windows 7 power optimization Less than 2% CPU activity when the system is idle No disk activity when the system is idle Reduced number of OS activities that prevent use of CPU’s power-saving modes.

Power Efficiency – Timer Coalescing API Platform energy efficiency can be improved by extending idle periods New timer coalescing API enables callers to specify a tolerance for due time Enables the kernel to expire multiple timers at the same time BOOL WINAPI SetWaitableTimerEx( __in HANDLE hTimer, __in const LARGE_INTEGER *lpDueTime, __in LONG lPeriod, __in_opt PTIMERAPCROUTINE pfnCompletionRoutine, __in_opt LPVOID lpArgToCompletionRoutine, __in_opt PREASON_CONTEXT WakeContext, __in ULONG TolerableDelay ); Timer tick 15.6 ms Vista Periodic Timer Events Windows 7

Trigger Start Services

Impact of Background Activities Many activities in the background Performance Responsiveness Consumes resources Boot, shutdown, logoff, and so on Reliability Memory leaks System crashes and hangs Dependent application crashes Security Greater attack surface System privileges Successful attack may compromise entire system Power consumption Extra disk, CPU utilization Decrease in battery life Prevents idle efficiencies

Do We Really Need So Many Services? OEMs and third parties services Most services are not required during log-on Even more services are not required during boot Most services do not need to run 24x7 Conclusion: Most services can be launched on demand when needed Most services can be terminated on demand when needed Consider using Windows Tasks

Service Startup Types Prior to Windows 7 Automatic Start Your service is always there Launched as part of the boot sequence Slower startup time Bigger memory footprint Delayed Auto Start Just deals with Slow startup time Demand Start (manual) You must programmatically launch the service Why these services startup types are not enough? Automatic Start adds latency to boot and shutdown, and always consumes resources Demand Start is hard to program against and just resolve the startup problems

New In Windows 7 - Trigger Start Services Trigger Start services are started when needed and stopped when their work is completed The service should be running only if it has something to do. Windows 7 Available service triggers: Device interface arrival Joining or leaving a domain Opening or closing a firewall port Group policy change First IP address arrival Last IP address removal Custom events (ETW)
