Re: [SQU] Parent Cache

Then you are currently perhaps a bit short of options to balance the
load between the two parents.

What you can do is to look into the connect_timeout cache_peer option.
If you are lucky then the slow parent are also slow in accepting TCP
connections and in such case Squid can detect that it is slow.

If the slow parent is fast at accepting the TCP connections but slow in
processing the HTTP requests then there currently is no option to weight
the load share based on this. It is not an easy thing to measure as the
request latency also very much depends on the requested site, not only
the parent cache.

For load balancing between parents Squid has the following options:

a) ICP round trip weight
b) Rount-robin selection
c) TCP connection failure detection with automatic fallback on other
parents or direct mode depending on the configuration and Squid patch
level.
