You could set icp_query_timeout to a fixed value instead. It will stop
Squid from recalculating the ICP timeout when the parent gets slower and
instead consider it dead.

--enable-icmp collects round-trip times to origin servers using cached
ICMP ECHO queries. This is used to go direct when you are closer to the
origin site than your parents. I am not 100% sure how this really works
so I can't really say how it performs (I have never used it, nor studied
it in detail).
