Agenda • Introducing the Performance Troubleshooting Flow Chart • Using the flow to • Fix slow disk • Find memory pressures • Uncover network issues • Identify high processor utilization • Resource to help you back at work (c) 2011 Microsoft. All rights reserved.

Looking for disk latency • Common causes of high latency • We don’t care what disks • Direct Attached Storage (DAS) • Storage Area Network (SAN) • Network Attached Storage (NAS) • Internet SCSI (iSCSI) • Installed software may change performance metrics
Looking for disk queuing • Common causes of queuing • Now we do care about what disks • Queuing to local disk • Queuing over a storage network • Identify the problem and work with the storage team
Understanding disk load • Load only matters when we see latency and queuing • Correlating load • Disks • Processes • Talking with the storage team
Looking at memory pressure (c) 2011 Microsoft. All rights reserved.
Looking at memory pressure • Available memory is not unused memory • Why paging is not just the page file • The file system cache (c) 2011 Microsoft. All rights reserved.
Looking at application memory use • It’s all virtual • Monitoring overall memory consumption • How to identify consumers and leakers
Looking at application memory use • Remember it’s all virtual • Monitoring overall memory consumption • How to identify consumers and leakers
Looking for kernel memory pressure • Common causes of kernel memory depletion • Additional tools • Process Explorer shows kernel pool sizes • Poolmon shows memory pool consumers
Looking for kernel memory pressure • Common causes of kernel memory depletion • Additional tools • Process Explorer shows kernel pool sizes • Poolmon shows memory pool consumers
Looking for network problems • It’s just more I/O • Check end-to-end link saturation • Check the configuration of NICs • Don’t forget your network tools • Ping • Tracert • Pathping
Looking for processor problems • Look for overall load • Determine which process is hogging the processor • Be careful in a virtualised environment
How does virtualization affects performance troubleshooting?
How does virtualization affects performance troubleshooting? • Disk counters are not affected • Queuing is more likely as resources may be shared • Memory counters may not be affected • Counters values may be false when using any type of dynamic memory allocation • Network counters are not affected • Queuing is more likely as resources may be shared • Processor counter are completely unreliable • Use native virtualisation tools to monitor processor utilisation (c) 2011 Microsoft.
