How does Java Flight Recorder (JFR) impact performance or memory usage?

Java Flight Recorder (JFR) is a Java Virtual Machine (JVM) feature that allows for detailed monitoring and profiling of Java applications. While its benefits are significant in terms of performance insights, there are specific impacts on performance and memory usage due to its operational characteristics.

        <?php
        // Example of how to enable JFR
        $jfr_command = "java -XX:StartFlightRecording=duration=60s,filename=jfr-recording.jfr MyJavaApp";
        exec($jfr_command);
        ?>

Enabling JFR may incur a small overhead primarily during the recording phase. The memory footprint can increase due to the events being captured, but this is often outweighed by the insights gained during analysis. It's essential to monitor and configure JFR settings according to the application's needs to minimize performance impact.
