14.1.4 What is code profiling?

Code profiling is a form of measuring the execution time and the execution count of

functions, blocks or instructions. It can be used as a metric for the complexity of a

system and can highlight where computing time is spent. This provides a great

insight into the running system and is essential when identifying code that is exe-

cuted frequently, potentially placing a high load onto a system. The code profiling

information can help to easier optimize a system, as it accurately shows which blocks

take the most time and are worth optimizing.

This feature also requires a J-Trace that supports streaming trace.
