Check your cabling, network interface statistics, and that the server and
the switch agrees on the type of network.

The symptoms you describe is very common for network errors such as bad
cables, server and switch disagreeing on the network type (i.e. one
100Mbps full duplex, the other half duplex) and similar errors causing
significant packet loss.

It's a good estimate (might be one or two off for other files, plus it
also includes some objects discarded before completely cached due to
aborts etc..).
