|Measures the time needed to evaluate {{Code|$expr}} and outputs a string to standard error or, if the GUI is used, to the Info View.<br/>An optional {{Code|$label}} may be specified to tag the profiling result. Helpful See {{Function||#prof:track}} for further notes:* Profiling might change the execution behavior of your code: An expression that might be executed iteratively will be cached by the profiling function.* If a value has a compact internal representation, evaluation time will be very low, even if it may take a long time to iterate through all results.

|Measures the memory allocated by evaluating {{Code|$expr}} and outputs a string to standard error or, if the GUI is used, to the Info View. An optional {{Code|$label}} may be specified to tag the profiling result. Helpful See {{Function||#prof:track}} for further notes:* Profiling might change the execution behavior of your code: An expression that might be executed iteratively will be cached by the profiling function.* If a value has a compact internal representation, memory consumption will be very low, even if the serialized result may consume much more memory.* In Java, memory profiling can only be approximative: To improve the measurement, main-memory will be garbage-collected before and after evaluation.
