disable trace

When you test your applications for performance, ensure that you use the standard version of Flash Player rather than the debugger version of Flash Player, if possible. The debugger version of Player provides support for the trace() method and the Logging API. Using logging or the trace() method can significantly slow player performance, because the player must write log entries to disk while running the application.

If you do use the debugger version of Flash Player, you can disable logging and the trace() method by setting the TraceOutputFileEnable property to 0 in your mm.cfg file. You can keep trace() logging working, but disable the Logging API that you might be using in your application, by setting the logging level of the TraceTarget logging target to NONE, as the following example shows:


myLogger.log(LogEventLevel.NONE, s);

For performance testing, consider writing run-time test results to text components in the application rather than calling the trace() method so that you can use the standard version of Flash Player and not the debugger version of Flash Player.
