Usage

• The custom node is called KSampler (timer).

• The node is found under add node > sampling > KSampler (timer).

Behavior

This node is just a wrapper around the native KSampler. This node adds two outputs to the KSampler:

• GENERATION_TIME_STRING
  The time in seconds as a float string with 2 numbers after the comma.

• GENERATION_TIME
  The time in seconds as a float.

Batches

The time returned is for the whole batch.

You may have to divide the generation time by the batch size to get the average generation time. (See examples on how to do it.)

Examples
