There is a need for a more powerful x86 router. Price is not critical. Tell me please, is there a difference in performance between processors Intel Core i7 and i5 one generation, and working on the same frequency? for example Core i5 2500K and Core i7 2600K.
Technically only difference in increased volume of cache memory and supporting hyper-threading technology.
Does it make sense to disable this technology manually in BIOS?

I'd like to hear a response from the MikroTik command.

Regards.

Thank.
But how about hyper-threading technology? Enable or Disable?

depending on configuration, if you have a lot of interfaces, you can assign cores to interfaces and distribute load that way

How to assign selected core to work only with selected interface at MikroTik x86 machine?

Interesting question, waiting for the answer too.

Does it means that if i manually assign ether1 to cpu0, then other interfaces or processes can`t use cpu0?

And one more question, please.

In 1core x86 router configuration on ethernet interfaces starts drops at about 80-90% CPU load (mikrotik indication)
2core - at 40-45%
4core - 25-30%
and so on ...

Why is this?

To manually assign core per interface:
1. disable RPS (/system resource rps)
2. Manually assign IRQ (/system resource irq)

On "system - resourse - cpu" i can see 8 cpu`s (Intel core i7 3770 - 4 phisical cores + 4 threads by hyper threading function).
Tell me please, what cpu number match phisical cores?
ie 0,1,2,3 or 0,2,4,6?
I ask the question because I do not want to assign two important interfaces per one physical core.

So load will increase on the first core unless you use cpu affinity?

No, the system load balance it, but you can using manual control if you not trust the algorithm.
