Each I/O read() Squid performs in receiving a response is assessed as to 
what buffer free space and pool speeds are affecting it. If a client 
disappears midway the pool(s) that client caused to be applied no longer 
are. So the transaction may speed up if the server and network can do 
more speed.

"range_offset_limit N" only affects the initial starting point for a 
transaction. If a client wants to start reading a range somewhere in the 
first N bytes Squid will request the full file in order to cache it for 
future requests. Otherwise only the range the client wants will be 
requested - and cannot (yet) be cached.
