A few thoughts:
1) 512KB/sec would be 4Mbps. Are you sure this is what you really
have? Most cable and network vendors talk about performance in terms of
bits per second, while downloads are usually measured in bytes per
second. (I.e. don't mix up bits and bytes...) (25 KB/sec is 200Kbps.)
2) You may have congestion on your cable segment. The cable modem
segment is shared by all subscribers in an area (typically a small
neighborhood or block or street).
3) The problem could exist at the end of the connection -- not sure how
you're estimating bandwidth. Many sites have considerably less than
4Mbps to offer to each and every client that does a download. Some
sites even intentionally throttle back bandwidth to prevent a single
client with a good connection from starving out clients with poorer
connections.
4) There could be a problem at your ISP.
5) Its pretty unlikely that the problem exists at your end. But you
could check that everything has negotiated duplex, speed properly, etc.
And you could try replacing cables in case you have a particularly
crummy cable. (Look at the statistics in nge using netstat -i to see if
you have high error counters.)
