Whole of Squid speeds up even for other never-seen-before URLs? or just
the one URL request speeds up?

The former is usually because Squid is loading caches and generating
indexes in memory. It can service traffic while doing that, but only at
a slow rate.

The later is usually because Squid is caching. A MISS request from the
network is almost always slower than a HIT request from local machine
memory or disk. MISS involves DNS lookups, TCP connection setups
(multiple sometimes) and processing of Squid<->Internet traffic on top
of what the HIT would be doing.

Are you using the Debian squid3 package? if not please install that one
instead of the old "squid" package.

What is the output of "squid3 -v" ?

What is your squid.conf content?

What time does wget command from the Squid machine take to fetch the
same slow URL?
