Hey Ahmad,
It's possible to use another proxy software. If you do not need any specific functions that squid has you can easily run a forward proxy that will probably be simpler to operate, unless. you have something specific that only squid gives.

Hello Alex , Thanks for your reply , I thought as long as squid is only as forward proxy only and no https , we may disable some built in squid features that is not required in my purpose for getting lower CPU consumption such as use minimum squid functions . We don't have any bottleneck in squid . The only issue is when there is a very high traffic that will use the CPU at higher scale . So my only goal is decrease squid CPU consumption as much as I can . So I build local dns server to fasten the lookup , but still don't see any rich topics online for my goal .

I do not recall any _major_ changes in that area, but the http_port worker-queues option may be of interest to those looking for performance optimizations. > Is there any best practice I can use to lower the cpu usage or response > time ? YMMV, but I would start by using (the right number of) SMP workers with cpu_affinity_map and worker-queues. More on that at https://wiki.squid-cache.org/Features/SmpScale#How_to_configure_SMP_Squid_fo r_top_performance.3F Beyond that, one would have to analyze your Squid performance to find out performance bottleneck(s) and then try to eliminate them or reduce their impact. > Like Deny caching on the HDD or server_persistent_connections off > similar directives Disabling persistent connections will make things _worse_ in many cases but YMMV. Whether cache_dirs (and even shared memory cache) slow down or speed up an average response depends on your environment -- measure and adjust/remove accordingly.
