Consider this a reply to Kinkie and Eliezer. Yes, I expect my setup is unusual, but that's why I'm trying to get advice from others who might have a similar setup. I run the proxy as the main destination for a wildcard DNS. This is our many tenants use URLs in the wildcard domain (lets call it "*.wild.com") and the proxy connects them to the various backend services based on the hostname such as: acme-www.wild.com connects to the WWW server for Acme customer beta-www.wild.com connects to a similar but different WWW server for Beta customer. For each customer there are 5-10 unique hostnames to keep the services separate. We do this as it is much simpler than URL-rewriting (or at least it seemed so to me at the beginning). In addition, our proxy listens on about 8 different ports (80/443/8080, etc) for different services. The different ports require 7 ACLs that excludes the other ports that are not for that one service/port combination. I can get more specific if anyone is interested. I use make+M4 macros to generate the squid.conf file from a source file and then separate all the customers into individual configuration files based on a conf.d directory. Zero caching is happening, it is all just forwarded traffic. When I started with ~50 customers, squid cpu was <5% at all times. Now with closer to 200 customers it sticks around 20%, so I'm just thinking about the future. And if things keep going well, I can only expect the number to rise. Thanks for all the replies! And if anyone is wondering how I counted lines I used something like this to eliminate comments and blank lines: egrep -vc '(^#|^$)' squid.conf Owen On Sat, Jun 28, 2014 at 3:50 PM, Kinkie <gkinkie@xxxxxxxxx> wrote: > On Fri, Jun 27, 2014 at 9:51 PM, Owen Crow <owen.crow@xxxxxxxxx> wrote: >> I am running a non-caching reverse proxy using version 3.3.10. >> >> My squid.conf is currently clocking in 60k lines (not including >> comments or blank lines).
