Maybe yes. Maybe no. pinger is a tricky one. It is used to record RTT
for each server connection Squid might possibly make (each IP for each
server a request might go to) so the fastest one can be selected as
first choice when theres a set of destinations.

In theory its great for preventing long-latency connections. But it dont
work often enough yet for it to be a desired thing. The distance
weighted load balancing between cache_peer's algorithm gets most gain.
