Many thanks Amos and Ralf,
i have a simple proxy with no proxy hierarchy, then i will set the
parameter to "none".

It is most useful for peer connections where the peer selection

Like reverse proxies?
Like weighted round-robin, ICP, HTCP.
It is also used with persistent connection selection as a small
optimization to prioritize faster connections to be selected for re-use
rather than slower connections. This makes a big difference for servers
operating behind an IP load balancer.
This feature is always an optional one. In absence of NetDB RTT data
algorithms using it assume that all TCP connections are equally fast.
In a "normal" proxy setup (users are behind 4 proxies which connect
them to the Internet), does use of Netdb make sense?
Depends on how focused one is on latency and what RTT differences the
proxy is detecting. If you don't care about a few ms on some connections
or the RTT variation between connections to a server is normally under
1ms then it can be better to use the memory and CPU cycles for other
things like cache_mem.
