I was reading your post and tried to use AUFS. I am running Linux (redhat 8.0)
It kept giving me an error. FATAL: Unknown cache_dir type 'aufs' Squid Cache (Version 2.5.STABLE3-20030612): Terminated abnormally. CPU Usage: 0.000 seconds = 0.000 user + 0.000 sys Maximum Resident Size: 0 KB Page faults with physical i/o: 207 Aborted Do you know what I can do. Do I need to redo the cache directories.

I would recommend the following: Actually, this ("mainly because it's not multi-threaded") is not true. Threading costs syncronisation overheads, and only adds single-process CPU scalability - and squid gets that very effectively by running multiple instances. Squid using poll() can drive linux to 70% CPU time in poll(), 100% total time used - that is something that threading -does not help-. Squid's non-blocking single-threaded model is -nearly- optimal for high performance networking. > - Change your cache_dir type to something other than the default ufs - > use aufs for Linux and diskd for BSD.
