Development

Running Performance Tests

To run automated performance tests and collect a CPU profile (JFR):

./gradlew :perf-tester:runIde

The test will automatically:

1. Open a set of Concord files (including a large stress-test file).
2. Trigger code analysis and highlighting.
3. Collect JFR data and exit.

Result: The JFR report will be generated at build/reports/perf-<timestamp>.jfr (e.g. perf-20260226-121530.jfr). You can open this file in IntelliJ IDEA or Java Mission Control to analyze CPU usage and allocations.
