Perfetto tooling for analyzing Android, Linux, and Chromium browser performance – Microsoft-Performance-Tools-Linux-Android
Introduction In the last blog post, we introduced the cross platform open-source .NET Core Microsoft-Performance-Tools-Linux-Android tooling. Recently, we just released version 1.2 adding Perfetto support, which we will cover here. Perfetto is Google’s open-source tracing ecosystem covering Linux kernel tracing (and user-mode) and built into Android. Perfetto is best-in-class for Android tracing. The Perfetto ecosystem covers System Profiling, In-App Tracing, Trace Viewer, and Trace Analysis. The Perfetto ecosystem is Google’s equivalent of the Microsoft Event Tracing for Windows (ETW) ecosystem. We wo...

WPA: Table & Graph Configurations (Part 2)
In Part 1, we discussed the different types of columns options available in WPA's table views and how those views can be configured. This blog will continue the series by digging into how to configure columns for different graph styles that can show numeric aggregations, time, and hierarchical data: Graphing Overview Before we dive into how to configure the tables and graphs, we should do a quick introduction to the Group & Graph bars in WPA's tables. Any column in the Data Area or Graphing Element Area can be aggregated (see Part 1 - Aggregation). Aggregated columns are graphed wh...

Introducing EcoQoS
EcoQoS is a new Quality of Service (QoS) level introduced to Windows that developers can now opt-in to run their work efficiently, leading to better energy efficiency/increased battery life, reduced fan noise and power/thermal throttling.
WPR fails to start, insufficient system resources?
From time to time, I get questions about insufficient system resource error (0x800705aa) when starting the trace using WPR. The error can be frustrating, especially when there is enough memory and storage space left on the system. Some people try to solve the issue by increasing the system resources such as killing some apps and services. It does not help. I agree. It is frustrating to see generic error messages like this which can mean many things. Let us find out what causes this error and how to resolve the situation. Cases where WPR throws ERROR_NO_SYSTEM_RESOURCES error This insufficient system resource er...
