I think they are default on if you look at references

Hi Alex
Thanks for your feedback, in this case enable client_persistent_connections and server_persistent_connections could help or is better to keep it disable?

Best regards

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.

Alex.

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
