Description

https://docs.celeryproject.org/en/stable/userguide/optimizing.html#prefetch-limits
The first paragraph talks about The prefetch limit is a limit for the number of tasks (messages) a worker can reserve for itself. .

The second paragraph talks about The workers’ default prefetch count is the worker_prefetch_multiplier setting multiplied by the number of concurrency slots [‡] (processes/threads/green-threads)..

It's not clear the difference/links is between the prefetch limit and the prefetch count. Are they exactly the same things but different terminology is used in different paragraphs? If they are different things, it's clear you can change the prefetch count by editing the worker_prefetch_multiplier but no mention is made of what the value is for the prefetch limit or if it can be changed.

This is confusing.

Suggestions

If the prefetch count and prefetch limit are the same things, then the wording should be consistent across paragraphs. Optionally, if users may know them as either term, then something like the prefetch count, also sometimes known as a prefetch limit, is ... could work.

If they are different things then more description should be added to the prefetch limit to explain what it's value is and how to change it (or if it's not possible).

Thanks in advance! :)
