I am running Squid3 3.3.8 on Ubuntu 14.04. Squid3 has been installed from the Ubuntu package repository. In my scenario, Squid has to cache big files >= 1 GB. At the moment, I am getting very bad transfer rates lower that 1 MB/sec. I have checked the connectivity using iperf3. It gives my a bandwith of 853 Mbits/sec between the nodes. I have tried to investigate the problem and recognized that when there is no cache hit for a requested object, the Squid process reaches shortly after startup 100 % of one CPU core. The download rate drops down to 1 MB/sec. When I have a cache hit, I only get 30 MB/sec in my download. Is there someting wrong with my config? I have already used Squid 3.3.14. I get the same result. Unfortunately, I was not able to build Squid 3.5.5 and 3.5.6.
