Performance Tuning Overview
A process rather than an event Performance tuning process consists of: Establishing a baseline Recognizing bottlenecks Tuning performance Performance Tuning Overview Performance tuning A process rather than an event Performance tuning process consists of: Establishing a baseline Recognizing bottlenecks Tuning performance Microsoft Specialist Guide to Microsoft Windows 10 (Exam , Configuring Windows Devices)

Establishing a Baseline
To recognize system bottlenecks, you must first establish a baseline Baseline Set of performance indicators captured when system performance is acceptable Performance indicators are often called counters Display values for system characteristics Establishing a baseline Verify no unusual activity is happening on the workstation Measure performance indicators over time Establishing a Baseline To recognize system bottlenecks, you must first establish a baseline Baseline Set of performance indicators captured when system performance is acceptable Performance indicators are often called counters Display values for system characteristics Establishing a baseline Verify no unusual activity is happening on the workstation Measure performance indicators over time Microsoft Specialist Guide to Microsoft Windows 10 (Exam , Configuring Windows Devices)

Recognizing Bottlenecks
Occur when a limitation in a single computer system component slows down the entire system Disk bottlenecks Occur when applications want to read and write information to the physical disk faster than the disk can manage To increase disk performance Upgrade the disks Implement mirrored Storage Spaces Move the paging file to a nonsystem disk Recognizing Bottlenecks Bottlenecks Occur when a limitation in a single computer system component slows down the entire system Disk bottlenecks Occur when applications want to read and write information to the physical disk faster than the disk can manage To increase disk performance Upgrade the disks Implement mirrored Storage Spaces Move the paging file to a nonsystem disk Microsoft Specialist Guide to Microsoft Windows 10 (Exam , Configuring Windows Devices)

Memory bottlenecks Occur when applications require more memory than is physically available To reduce the use of virtual memory Increase the amount of physical memory Run fewer applications at once Recognizing Bottlenecks Memory bottlenecks Occur when applications require more memory than is physically available To reduce the use of virtual memory Increase the amount of physical memory Run fewer applications at once Microsoft Specialist Guide to Microsoft Windows 10 (Exam , Configuring Windows Devices)

Processor bottlenecks Occur when there is too much work for a processor To resolve processor bottlenecks Change to a faster processor Add additional processors Change to a multicore processor Recognizing Bottlenecks Processor bottlenecks Occur when there is too much work for a processor To resolve processor bottlenecks Change to a faster processor Add additional processors Change to a multicore processor Microsoft Specialist Guide to Microsoft Windows 10 (Exam , Configuring Windows Devices)

Network bottlenecks More common for servers than computers running Windows 10 Multiple computers accessing a single server may overwhelm the network connection to the server Upgrading a network may involve replacing network cards, cabling, and switches Recognizing Bottlenecks Network bottlenecks More common for servers than computers running Windows 10 Multiple computers accessing a single server may overwhelm the network connection to the server Upgrading a network may involve replacing network cards, cabling, and switches Microsoft Specialist Guide to Microsoft Windows 10 (Exam , Configuring Windows Devices)

Tuning Performance Steps Create a baseline for the computer
Compare the baseline to current indicators Identify possible causes for variations Identify possible fixes for variations from the baseline Select a fix to implement Implement the fix and monitor for changes If not resolved, undo the fix and repeat step 5 If resolved, document solution for future reference Tuning Performance Steps Create a baseline for the computer Compare the baseline to current indicators Identify possible causes for variations Identify possible fixes for variations from the baseline Select a fix to implement Implement the fix and monitor for changes If not resolved, undo the fix and repeat step 5 If resolved, document solution for future reference Microsoft Specialist Guide to Microsoft Windows 10 (Exam , Configuring Windows Devices)
