Hey Eric and David, I am thinking about the best place to put a note acl. What is the actual requirement? Do you want to limit a specific client or all of them? I have not used delay pools for a very long time so I am not sure about what you want these to do.

We had the same restrictions with the fast or slow ACLs. Have you thought about creating a squid helper that calculates your needs? So maybe you can get around this by using the acl "note" acl note xxx xxx which turns your helper results (slow) into "fast". Le 05/09/2022 à 14:56, PERROT Eric DNUM SDCAST BST SSAIM a écrit : Hello,
We use directives "reply_body_max_size", "request_body_max_size" and "delay_access" to limit upload, download and passband in our infra. This configuration existes since a while, but we have noticed that with squid v4.16, our delay pool didn't react as we wanted anymore. We were excpeting improvment upgrading squid to v5.6. But it got worth : - restriction still didn't work - and squid had a segmentation fault each time some acl where used Thanks to Alex Rousskov (bug 5231), after some investigation, it appears that we used "slow" acl (proxy_auth an time acl) where only "fast" acl where authorized...). The bug is still open as squid has not flagged the problem in cache logs, My email, is to show you our configuration and the behaviour we espect, and the behaviour we finally have. 1 - squd v4.12 : we expect to limit downlod/upload and passband during working time for all login except those starting with cg_* " ###### Gestion de bande passante ########## acl bureau time 09:00-12:00 acl bureau time 14:00-17:00 # Comptes generiques acl my_ldap_auth proxy_auth REQUIRED acl cgen proxy_auth_regex cg_ reply_body_max_size 800 MB bureau !cgen request_body_max_size 5 MB # La limite de bande passante ne fonctionne plus avec le BUMP # A tester ... delay_pools 1 # Pendant time sauf cgen, emeraude delay_class 1 4 delay_access 1 allow my_ldap_auth !cgen !emeraude delay_access 1 deny all # 512000 = 5120 kbits/user 640 ko # 307200 = 3072 kbits/user 384 ko delay_parameters 1 -1/-1 -1/-1 -1/-1 107200/107200 ################################################## " => with this configuration, the delay pool seemed not to work anymore, so we upgraded squid to v5.6.
