Well, of course. If you're connecting to a webserver, you're presumably
going through an Internet-connection, which usually is not that fast.
You'll get more through the line, since your connection speed is your

If you're connecting to a 486, it does not have enough computing power
to keep up with the compression, especially not if you're doing so over
an 100Mbit-line. Then, not your connection speed, but your processor is
the bottleneck.
