I'd like to understand the output when debug is set to true in config.php.
Below is a typical portion of the output:

Debug: (0.010835) - (usage: 1629268) - (peak: 1664252)
loading events functions

What is the meaning of the numbers inside the three sets of brackets?

The first one is elapsed time (seconds), and the other two are memory usage and peak memory usage (bytes).

Thanks
