Method: Puma::DSL#threads

Defined in:
lib/puma/dsl.rb

#threads(min, max = min) ⇒ Object

Configure the number of threads to use to answer requests.

It can be a single fixed number, or a min and a max.

The default is the environment variables PUMA_MIN_THREADS / PUMA_MAX_THREADS (or MIN_THREADS / MAX_THREADS if the PUMA_ variables aren’t set).

If these environment variables aren’t set, the default is “0, 5” in MRI or “0, 16” for other interpreters.

Examples:

threads 5

threads 0, 16

threads 5, 5
