    Measures the time to parse a 1 MB CSV file, consuming the first field of each row.

    Using Oracle Flight Recorder

    To record a Flight Recorder file from a JMH run, run it using the jmh.extras.JFR profiler: > csv-bench/jmh:run -prof jmh.extras.JFR -t1 -f1 -wi 5 -i 10 .*CsvBench

    This will result in flight recording file which you can open and analyze offline using JMC. Start with "jmc" from a terminal.
