The machine where that ip_conntrack came from, is running two squid
processes, one on each processor, and clients are distributed evenly
over the two processes. 3128 and 3228 are the two listening ports
of those squid processes.
Such a conntrack shape will be the normal case for iptables running
on a server, more extreme than when it's running on a routing firewall.
As you asked for ideas about "better" hashes, could you possibly try
using CRC32 over the concatenation of the key values?
best regards
Patrick
