Tested with or without all those ACLs? They do make a difference to
speed, even the fast ACL tests.
I would expect them to, but my issue isn't with the overall speed, but
rather with the relative speed of the two versions when running the
same ruleset. It appears that 3.1 is significantly slower under these
conditions than 3.0.
pid_filename /var/run/squid.pid
cache_dir null /tmp
client_db off
cache_access_log syslog squid
NP: Squid needs a syslog format spec. Same as you would use in the
syslog config. "syslog:daemon.1" or some such. And the directive name
is now just "access_log"
it is documented as the facility and severity being optional, and the
format spec is given 'squid'
There is about 30% CPU load increase as well as the raw speed drop.
That 30% is IMO what you are measuring. When topping out the CPU it
obviously can't handle many more RPS.
* adding IPv6 support
- copying, checking version and text'ifying larger IPs a lot is SLOW.
- looking up DNS twice (AAAA and A) is relatively slower.
- failover when connecting via a network with broken IPv6
connectivity results slower server connect times. any transit network
blocking ICMPv6 breaks *your* IP failover.
3.1 was compiled without IPv6 support (I'll report all the config
options in the morning)
Ok, the config options for 3.0 and 3.1 are:

is there anything in here that hurts the performance and I should remove
(or anything I should have in here for best performance)
Nothing in that lot.
