It is, that mattered on 1Gbit links with multiple clients, ie any disk operations in VMs while there is vMotion running on the same links - you could see how everything started to crawl (and returned back after vMotion completed). For 10Gbit you need way, way more load for it to matter.
> You can also use it to use multiple NICs without bonding/teaming
You MUST (as in RFC) use multiple links without bonding and I learned to not to use LACP the hard way (yea, reading docs before is for pussies).
After second attempt I understood the implication (multiple NICs in the same IP network), but this is a self inflicted wound, usually. You don't even need a physically separate networks (VLANs), but using separate IP networks works fine, it's up to initiator to use RR/LB on them.
> it would pick "first available" NIC to send it
Yep, the usual magic of doing things to be easier for average folks. In the same vein - you need to disable Proxy ARP in any modern non-flat network or you will get shenanigans what would drive you mad.
