*granularity*

The value of this variable should be a positive fixnum specifying the number of machine clock ticks (defined below) between each sample of the stack taken during data collection by the runtime analyzer. The initial value is 1, indicating one clock tick between each sample. The larger this value is, the more clock ticks between samples and the smaller the frequency of sampling.

The units of this variable are computer clock ticks and the value specifies the number of ticks between samples. A clock tick is an internal, machine dependent span of time. A tick is typically between 1/50 and 1/100 of a second. Some tens of thousands of instructions are executed by the machine in that time.

This variable is ignored by the space runtime analyzer.

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