*significance-threshold*

The value of this variable should be a number between 0.0 and 1.0. It is used as a significance threshold by the runtime analyzer display functions, show-call-graph and show-flat-profile. Functions which contribute less than the significance threshold are not displayed. This allows the runtime analyzer display functions to suppress reporting of functions whose total contribution is considered insignificant in the total profile data sample. Comparison is made between the value of this variable and the ratio of the sum of the function and all of its callees, recursively and the total data recorded in the whole profile sample. The initial value of this variable is 0.01.

The function prof:show-all causes this variable to be set to 0.0.

This variable only affects display of runtime analyzer data, not the collection of data. If you want to see more or less, redisplay after resetting this and other runtime analyzer display variables as desired.

The value of this variable and the other runtime analyzer display variables, *hidden-packages*, *hidden-functions*, *hidden-space-functions*, and *fractional-significance-threshold*, can be reset to their initial values by reset-profiler-display-defaults.

See runtime-analyzer.htm for general information on the runtime analyzer.
