I'm not using pipeline_prefetch, because pipeline_prefetch breaks the
NTLM/Kerberos authentication.
Enabling pipeline_prefetch introduces other problems as well. There
might be some very special use cases that benefit from pipeline_prefetch
today, but, in general, that directive should not be used (and the whole
feature should be removed from Squid until it is properly implemented).
I cannot currently answer your primary questions on this thread. I hope
somebody else will guide you through this triage.

Hi
Sometimes my users complains that the internet navigation thought
Squid is very slow.
After checking the access.log, I can see a lot of ABORTED messages
like this
1715537802.589 2 10.103.12.94 NONE_NONE_ABORTED/200 0 CONNECT
api.telegram.org:443 - HIER_NONE/-:- - mac="00:00:00:00:00:00"
accessrule:%20global_whitelist%0D%0A exterr="ERR_CLIENT_GONE|WITH_CLIENT"
1715537183.180 99993 172.16.31.205 TCP_MISS_ABORTED/000 0 POST
http://pjcpd-dlpend01.hlbank.my/GECommunicationWS.asmx -
HIER_NONE/-:- - mac="00:00:00:00:00:00"
accessrule:%20global_whitelist%0D%0A exterr="ERR_CLIENT_GONE|WITH_CLIENT"
I have imported the access.log into my ELK machine and I can see that
during the time that the users complained about the slowness there is
a huge spike of NONE_ABORTED messages.

Now my question is:
1. What can cause this kind of issue? It's a squid server issue,
network (firewall, switch, router, …), or client?
2. Why the number of NONE_ABORTED requests is almost 4 time more than
normal request?
Best regards
