PerfView

PerfView is a performance analysis and diagnostics tool designed for developers and system engineers who need to understand application behavior and troubleshoot performance issues on Windows. Capture detailed event traces from your system, including CPU usage, memory allocation, disk I/O, and network activity, then analyze the data to identify bottlenecks and optimize your code.

The tool excels at helping you drill down into complex performance problems. View flame graphs and timeline visualizations that reveal exactly where your application spends its time. Filter and search across millions of events to isolate the root cause of slowdowns, memory leaks, or unexpected resource consumption.

Whether you're profiling a single process or analyzing system-wide behavior, PerfView provides the instrumentation and analysis capabilities needed to make data-driven performance improvements. Get started with built-in scenarios for common profiling tasks, or create custom traces tailored to your diagnostic needs. PerfView helps teams ship faster, more responsive software.
