Performance Analyzer Qt

The tool provides structured profiling for Qt applications by collecting runtime metrics such as CPU usage, memory footprint, frame rate, and event loop latency. It targets developers, performance engineers, and QA teams who profile apps during optimization, regression testing, or porting to new platforms. Data is gathered across desktop and embedded Qt platforms, enabling cross-environment comparisons.
Conceptually it operates by combining lightweight instrumentation with statistical sampling to minimize overhead. It profiles the application while it executes representative workloads, records per-frame timings, and aggregates results into reusable timelines and summaries. A baseline benchmark can be captured and later compared to detect regressions or confirm gains.
Benefits include Qt-specific insight into the main UI thread, signal-slot latency, and rendering bottlenecks in Qt Quick or Widgets. It identifies hot paths by listing top functions and call counts, and it can export results to standard formats for audit trails. The tool is designed to be deterministic across runs, aiding regression testing and performance budgets.
Core features include CPU and memory tracking, FPS and latency measurements, hotspots and call graphs, timeline charts, and report exports. Use cases span initial profiling of new Qt apps, investigating stability during UI transitions, and validating performance improvements after refactoring or porting to new platforms. Results can be filtered by component (UI, rendering, logic) and exported as JSON, CSV, or human-readable reports.
