<p>Hi Alex<br>
Thanks for your feedback, in this case enable
client_persistent_connections and server_persistent_connections
could help or is better to keep it disable?</p>
<p>Best regards<br>

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.

Alex.

Hi
<br>
<br>
Sometimes my users complains that the internet navigation
thought Squid is very slow.
<br>
<br>
After checking the access.log, I can see a lot of ABORTED
messages like this
<br>
<br>
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"
<br>
<br>
1715537183.180 99993 172.16.31.205 TCP_MISS_ABORTED/000 0
POST <a class="moz-txt-link-freetext" href="http://pjcpd-dlpend01.hlbank.my/GECommunicationWS.asmx">http://pjcpd-dlpend01.hlbank.my/GECommunicationWS.asmx</a>
- HIER_NONE/-:- - mac="00:00:00:00:00:00"
accessrule:%20global_whitelist%0D%0A
exterr="ERR_CLIENT_GONE|WITH_CLIENT"
<br>
<br>
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.
<br>
<br>
<a class="moz-txt-link-freetext" href="https://i.postimg.cc/6QR79GWk/6e727e86-de3d-4f3b-bd9e-04c04052ca2e.jpg">https://i.postimg.cc/6QR79GWk/6e727e86-de3d-4f3b-bd9e-04c04052ca2e.jpg</a>
<br>
<br>
Now my question is:
<br>
1. What can cause this kind of issue? It's a squid server
issue, network (firewall, switch, router, …), or client?
<br>
2. Why the number of NONE_ABORTED requests is almost 4 time
more than normal request?
<br>
<br>
Best regards
<br>
