$TraceBuiltins

A Boolean Built-in variable when True collects function evaluation statistics.

Setting this variable True will enable statistics collection for Built-in functions that are evaluated.
In contrast to TraceBuiltins[] statistics are accumulated and over several inputs,and are not shown after each input is evaluated.

By default, this setting is False.

• • $TraceBuiltins = True

Tracing is enabled, so the expressions entered and evaluated will have statistics collected for the evaluations.

• • x

To print the statistics collected, use PrintTrace[]:

• • PrintTrace[]

To clear statistics collected use ClearTrace[]:

• • ClearTrace[]

$TraceBuiltins cannot be set to a non-boolean value.

• • $TraceBuiltins = x
