But normal is not necessarily good. Several bugs that have that type of effect have been fixed since 3.5.2 was released. If you can please upgrade to 3.5.20 ASAP, all releases before 3.5.19 have major security vulnerabilities. > Whether we can balance cpu processing capacity > <http://www.baidu.com/link?url=Rnht_DzfJLQPi_VnmfPjUfWfUdE4kaP1H7Vol-rTTZqKvF8npmGrx8-h947AFhU6-kqlwyWBW7W4ghqHWMs1iN1APnbkLMjrB7YI1PzephOCELHTqemcUEY1JH0mmw68> > for full squid process ! This focussing on balanced CPUs is counter-productive. With processes like Squid it is actually more efficient to use fewer CPUs at higher load than more CPUs at lower load. When one CPU core is doing a lot more of the work it means there is less contention between cores for access to RAM resoures, less delays incurred by UDP messaging between the Squid worker processes or waiting for atomic locks, and the unused core(s) can possibly be put into power-saving modes. All of which reduces latency or monetary costs. > > Because we use squid 3.5.2 and use cache_dir rock part .

You have used cpu_affinity explicitly in squid.conf, so that may alter what can be done with taskset.
