You can enable or disable performance profiling for mashup scripts. By default, profiling is disabled but statistics are configured to be sent to the console.

Performance profiling tracks execution time within the Presto Server for each EMML statement or declaration. This does not include network latency or any other processing time within the Presto Server, such as authentication or response formatting.

See Configuring Profiling Logging for instructions to enable profiling logging. See Mashup Profile Logs for information and examples on how profiling is logged.
