* e.g. libaom manages its own 4 threads when encoding AVIF images,
* and these are independent of the value set here.
*
* The maximum number of images that sharp can process in parallel
* is controlled by libuv's `UV_THREADPOOL_SIZE` environment variable,
* which defaults to 4.

* For example, by default, a machine with 8 CPU cores will process
* 4 images in parallel and use up to 8 threads per image,
* so there will be up to 32 concurrent threads.

* Further {@link /performance|control over performance} is available.
