This is true for all misses, cachable or not.

Each miss is alloted
1 TCP receive buffer in the receiving socket.
1 TCP transmit buffer in the sending socket.
1 Squid internal buffer of 16 KB.

The size of the TCP buffers varies depending on the system, kernel
config, software config and available memory. Usually somewhere in the
range of 16 to 64Kbyte.

It depends. Squid is perhaps not the optimal piece of software for such
use. I am not sure if there exists a proxy for offloading transmission
times from a HTTP server, but it is not very hard to write such piece of
software. Only problem is to find a efficient medium to use as a buffer.
