This option sets the level of trace information produced from trace-enabled user code.

The default setting, Disabled, preserves no tracing output, and results in all references to the tracing package being compiled out of code. This results in smaller, faster executables at the cost of execution tracing information.

For all other trace levels, tracing code is compiled in, resulting in larger and potentially slower executables. Selecting the Entry/Exit trace level results in trace event generation for every traceable function, which can have a negative effect on application performance. For more information about the tracing mechanism, refer to the Threads Module User’s Guide.
