Here is the squid.conf. If there are any optimizations I can do let me know.
The application that uses the "acl Citrix_Ports port 2598" rule is what I am
concerned about.
I probably commented out some safety/admin stuff due to troubleshooting.
Just as a note, the actual proxy process works fast; everything comes up
fine on the network. Just slow for certain apps.

Hello,
We have Squid version 3.1.19 running on our network and everything works OK
but we have noticed that rules set up to allow and deny access tend to be a
little slow.
So, if an application that we have set to be allowed on our network runs it
takes a while for it to connect becaue Squid is processing a rule for the
port for that application. Once Squid allows the application to connect (via
the "CONNECT" method) then everything works fine but it takes a long time
(30-60 seconds) for the rule allowing that application to connect to apply.
What can I do to fix this?
Start with showing us the access configuration please.
So far all we can say is "well, you start with optimizing the order", but
can't point you at particular details. For example do you have several
million regex patterns being processed? or a slow DNA lookup?
Once the order is streamlined for minimal tests performed it is easier to
debug test and see where the remaining bottlenecks are.
