That's why understood very fast what you actually were referring to.

Quote from the Postfix site:

IMPORTANT: These limits are designed to protect the smtpd(8) server
against flagrant abuse. Do not use these limits to regulate legitimate
traffic: mail will suffer grotesque delays if you do so.

Currently I am testing Amavisd-new as a pre-queue smtp-proxy, so I only
have six smtpd processes available (512 mb RAM and a server dating back to
the previous century). I still saw no delay in mail. That is, why I was a
bit puzzled why you received the mails not in one batch but over a longer
period.

What did you set these limits to?
