slow-frames-threshold

Specify a threshold to separate good frames from slow frames.

Syntax

-slow-frames-threshold <value>

Arguments

A value for the threshold frame rate in frames per second (fps). This value must be less than the value used for the fast-frames-threshold.

Default

40 fps

Actions Modified

collect, collect-with

Description

Use the slow-frames-threshold action-option to separate good frames from slow frames when analyzing frames. This cannot be used for the finalize action.

Example

This example performs the Basic Hotspots analysis, including user tasks specified in your code via the Task API. It marks frames below the slow-frames-threshold of 40 frames per second (fps) as slow, frames above the fast-frames-threshold of 100 fps as fast, and frames between 40 and 100 fps as good. The search-dir specifies the directory to search for symbol information.
