Squid doesn't cache objects - sorta

I am the maintainer of the Debian squid package, and one of the
users submitted the following report to the Bug Tracking System.
Does anyone have a clue as to what could be causing his problem?

I'm baffled.

Noticing that Squid seems a bit slow on my ageing pentium with Debian
2.1 installed, I went to investigate.

It turns out Squid is only using a fraction of its allotted cache
space, only populating the 00/00 directory. Worse, it doesn't
retrieve cached objects, on being requested an URL by a browser, it
dutifully fetches it, and logs a SWAPOUT and a TCP_MISS/200. Next
time it is accessed, it again logs a SWAPOUT, and a TCP_MISS/200, and
goes to fetch it anew, removing the old cached object (without any
RELEASE message, at least until some amount of objects are stored in
the cache - then I get the same behaviour, but with RELEASEs between

What on earth can the problem be? I've considered the existence of
options limiting % of disk to be used, my cache disk isn't that empty
- although more than large enough for the allotted squid cache. But
surely squid should serve cached objects anyway?

Grateful for any help with this!
