By the help of God.
Sorry I forgot to say that cache is disabled in this setup and the increasing traffic rate on the clients side can cause a bottle neck as it reaches the maximum
rates that the customers have.
Is there any option to limit the traffic?

This may be normal. A proxy cache like Squid moves objects closer to the clients, reduces upstream traffic and multiplexes transactions. All of which increase the traffic bandwidth efficiency. Allowing clients to receive their downloaded content faster, and thus users can browse through more pages faster.This type of user traffic increase can be just the result of users doing more.Notice that the WAN/eth0 traffic has decreased by ~30% despite this LAN increase.You can check the Hit Ratio in squid mgr:info report lines up with the increased efficiency.Cheers,

Average: lo 4191.83 4191.83 16976.00 16976.00 0.00 0.00 0.00 0.00

Squid Cache: Version 6.5-VCS
Service Name: squid
This binary uses OpenSSL 3.0.2 15 Mar 2022. configure options: '--with-large-files' '--with-openssl' '--enable-ssl' '--enable-ssl-crtd' '--enable-icap-client' '--enable-linux-netfilter' '--disable-ident-lookups'And I turned off persistence from client, icap and server sessions.What could be the problem?Thanks,Ben
