FAST presales advice, switchport voice vlan and perf. of CRS

Hello gents
I am new to Mikrotik (have one 2011uias-2hnd-in at home for personal use, but didnt spend too much time configuring it so far)
Now I am setting up a SOHO network for my customer and need FAST advice.

I need to create what cisco on their switches calls
switchport voice vlan XYZ
basically a 2 vlan trunk port with one voice vlan tagged and PC vlan untagged.

Can I do this on CRS 226?

Will this somehow influence wirespeed performance as claimed by Mikrotik?

Eventualy can you send a link, where I can find the setup?

There are reviews, that say, that with routed port the performance goes
deep down to couple Mbps. Was that already fixed, or is this a feature?
(I dont say anything, with pricetag as 226 has, it is ok and I want to use it as a switch
so I do not mind.)

If this is answered somewhere already, sorry for that, pls send me the link.

Thanks

Leo

Any of CRS switches can do this at wire-speed, because it is supported in the switch-chip.
The CRS port-based VLAN example 2 shows how to configure port for both tagged and untagged traffic.

CRS226 is primarily meant to work as a switch with some ports optionally configurable for routing, its CPU is not intended for high speed routing.

Thanks guys,
thats what i needed to have confirmed
