When you use very small pool sizes, the impact of the pre-buffering
effect of the TCP window can become quite significant.

delay_pools control how fast Squid will read data from the network,
the TCP window control how much data the kernel will buffer for Squid
to read.

No, each user will be allocated the least of the two available
amounts. No user will ever be allocated more than 400, and if all
your users compete for more than 16000 then each user will be
allocated less than 400.
