HT can add about 10-15% of CPU time when doing CPU inteensive tasks. squid usually contains no CPU intensive tasks.
Considering the statement that "hyper-threaded "cores" can actually be worse.", what is supposed to handle faster and concurrent connections on reverse proxy mode?: - Intel Xeon X3430 (2.40GHz, 2,80 GHz turbo, 4 physical cores, 4 threads) vs. - Intel Xeon E3-1230-V6 3.40GHz (3.50 GHz, 3.90 GHz, 4 physical cores, 8 threads)
I would count both of them as 4-CPU machines, e.g. would not configure more than four (apparently only three) workers for squid. Luckily kernels seem to understand hyperthreading CPUs and don't use HT unless needed, so the work will be spread over 4 cores in such case. -- Matus UHLAR - fantomas, uhlar@xxxxxxxxxxx ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
