[squid-users] 3.1.0.14 tproxy slow preformance
There are lots of tuning tips and articles. I am not sure some delay is natural, since it is a caching proxy. Try a lower cache size or none. It may be just latency, not bandwidth, that is impacted, but it will slow the individual user a lot.

pam_auth(8) System Manager's Manual pam_auth(8)
NAME
pam_auth - Squid PAM authentication helper
SYNOPSIS
squid_pam_auth [-n "service name"] [-t TTL] [-o] [-1]
DESCRIPTION
This helper allows Squid to connect to a mostly any available PAM database to validate the user name and password of Basic HTTP authentica-
tion.
-s service-name
Specifies the PAM service name Squid uses, defaults to "squid"
-t TTL Unless the -1 option is used, this specified for how long the connection to the PAM database should be kept open and reused for new
logins. Defaults to 60 seconds.
-o Do not perform the PAM account management group (account expiration etc)
-1 Specifies "One shot" mode, where a new PAM connection will be opened for each new user. This is how PAM is normally used and may be
required by some backend databases. The default is to reuse the PAM connection to maximize performance. (see -t above)
CONFIGURATION
The program needs a PAM service to be configured in /etc/pam.conf or /etc/pam.d/<servicename>
The default service name is "squid", and the program makes use of the 'auth' and 'account' management groups to verify the password and the
accounts validity.
For details on how to configure PAM services, see the PAM documentation for your system. This manual does not cover PAM configuration
details.
NOTES
When used for authenticating to local UNIX shadow password databases the program must be running as root or else it won't have sufficient
permissions to access the user password database. Such use of this program is not recommended, but if you absolutely need to then make the
program setuid root
chown root pam_auth
chmod u+s pam_auth
Please note that in such configurations it is also strongly recommended that the program is moved into a directory where normal users can-
not access it, as this mode of operation will allow any local user to brute-force other users passwords. Also note the program has not been
fully audited and the author cannot be held responsible for any security issues due to such installations.
