Windows Performance Recorder

The Windows Performance Recorder captures CPU, memory, and disk I/O metrics on Windows systems for profiling software and diagnosing performance issues. It supports targeting specific processes or system-wide collection, enabling repeatable measurements in development, testing, and incident response. The tool relies on native Windows mechanisms such as performance counters and ETW traces to minimize instrumentation overhead while producing portable data suitable for analysis and sharing with teammates. This approach avoids heavy instrumentation and preserves near production behavior.
Conceptually, the tool collects timestamped samples at a configurable interval, aggregates metrics per target, and exports structured data in CSV or JSON formats. Core outputs include cpu_percent, memory_bytes, read_bytes, write_bytes, net_bytes, timestamps, and pid, enabling straightforward reconciliation across runs. Optional features such as kernel counters, multiple targets, and per process filters allow deeper insight into subsystem interactions. Data readiness supports downstream analysis in standard analytics tools.
Who benefits includes software engineers optimizing code, QA teams validating performance under load, and operations staff monitoring baseline health. The unique value lies in native Windows integration, low overhead, precise per process metrics, and simple exports that fit into existing data workflows. Common use cases include detecting CPU bursts during IO waits, diagnosing memory growth patterns, and validating release tuning across Windows builds. The tool is designed for reproducible, shareable results in teams evaluating performance across development cycles.
