Web Garden Best Practices ? Not beneficial in most cases – only good for following specialized applications: ? Application is multiinstanceable ? Application is not CPUintensive ? Application has synchronous high latency backend (or sync high latency anywhere) ? Affinity Best Practices ? Affinitize pool to a POD (or hemisphere) ? In general, 4CPU is optimal case for affinity ? Try affinitizing NICs to CPUs too (distribute NIC interrupts) ? Done using SMPAffinitized = True amp。 using SMPProcessorAffinityMask ? Web Garden Best Practices ?

Use IIS Memory Recycling (private bytes – PeriodicRestartPrivateMemory) ? Watch for private bytes exceeding 800mb ? ASPNET OutOfMemory Exceptions attributed to address space fragmentation ? Reduce PeriodicRestartPrivateMemory to recycle sooner to prevent this from occurring (start at just under 800mb) ? CPU Throttling ? Use Windows System Resource Manager (Windows Server 20xx Ent and Data Center only) to control CPU usage ? Put mission critical applications in their own pools, and create WSRM policies for those pools to ensure they get CPU when they need it 參考資料 ? MSDN Webcast: IIS Architecture Overview ? IIS 新特性 ?
