Yes, and it does.
What it does not do is to wait for the usage to reach the high water
mark before starting to clean up. Instead the closer to the high
water mark the more aggressive it deletes objects.

On the contrary, by spending time when there is no requests to delete
objects performance is increased, as Squid then do not have to delete
objects at the same time as processing a request.

This would seriously impair performance. Every second Squid would need
to spend a lot of time on deleting objects, seriously impairing the
performance of requests at the time.
For Suqid performance you want an even and smooth performance, not
randomly blindingly fast and crawling.
You still have not answered how much traffic you are trying to push
via Squid.
