x86 multicore hyperthreading global queue tree best practice

Sat Jan 02, 2016 2:16 pm

i have a scenario in which i have to limit user traffic on a queue tree with global as parent. as i've read only one core is used for the queue tree. i have an i3-2120 with hypethreading enabled (so i have 4 virtual cores). is it better to disable hyperthreading so that routeros will use one of the two physical cores or is smart enough not to use the second virtual core if the first virutal core on the same physical core is maxed out (when hyperthreading is enabled)?

With HT is better. I tested a long time ago with Pentium 4 HT.
