The FAQ contains an entry on sparse checkouts [1], which notes:
# The new --depth feature naturally requires the client to be 1.5+, and
# will work most efficiently if the server is also 1.5+. However, the
# client will still behave correctly if the server is 1.4.x or lower;
# things will just be less efficient.
# This is because older servers do not understand — and therefore
# ignore — what the client tells them about "depth". So when a client
# requests a depth shallower than depth-infinity, older servers will
# send back more data than the client wants. However, a 1.5+ client
# will know it's talking to an older server and filter out this extra
# data. Thus, operations may take a while, because the server sends a
# lot of data over the network that the client then ignores, but the
# final result on the client side will be the same. (Note that older
# servers understand a recurse flag in the network protocols, and 1.5+
# clients send that flag based on the depth; this alleviates some of
# the extra network traffic penalty.)

You didn't mention what version your server is, but I suspect from
your description that your server hasn't been upgraded to 1.5 (or later).
Is this the case?
