The difference between bandwidth load, transaction load, and connection
load.

Squid load balancing algorithms are all message load balancing
algorithms. They do not balance bandwidth load. They all contain
connection (and/or message) bias.

This is explained in the
<http://wiki.squid-cache.org/Features/LoadBalance#Weighted_Round-Robin>
last few paragraphs about response time bias. The connection bias and
effects (other than latency) described in the round-robin section of
that page are also having an effect since this is a variation on
round-robin.
