Re: Are you implying...

It should be noted that Link aggregation (LAG, Portchannel, etc.) does not usually increase speed between two hosts because the decision on which bundle member is used is usually based on hash of L3 (IP) or L2 (MAC, not good in routed network) addresses of the peers. So it would generally be beneficial only when multiple clients are transferring data at the same time. And of course for redundancy.

You did not say you expect this but I see often the misconception that a single client would get faster speed with a LAG so I wanted to make it clear.

There are other ways to load-balance such as round-robin but those are usually not used because it may cause packets arriving out of order. I am not sure if that happens often on a simple network with a single switch but I'd still avoid it.
