I can see the /neighborsUdpPing/ in my logfile. I wonder, my local sites
which are local to me is faster than the parents. So it should have
SOURCE_FASTEST. I am using 2 parents in USA, the fastet RTT is 300ms to
these, and my local sites are at maximum 80ms or less. But generally squid
get local sites DIRECT, but not SOURCE_FASTEST ?

Yes I did this ! Also I can monitor ping info on the cache manager as well.

This make sence, may be this has to be explained on the FAQ as well :-)

I do not have any firewall. Is there a way to know why squid decide to
fetch from the DIRECT instead getting it from the parent. What I say is
that merely DIRECT is not sufficient, it should contain some reason :-|

Thanks again,
