netdb is the internal "Network Measurement Database" used by Squid for
calculating RTT and traffic loadings between itself and any given
upstream server.

In the recent Squid releases it requires --enable-icmp to enable ICMP
pinger but also pulls in additional details from ICP, HTCP and HTTP
connection and response timing. It seems to only be used by the
background weighted peer selection algorithms such as weighted-round-robin.
