Description:

I got a private network of two nodes.

case 1:
server->server
ipfs get: 1minute
scp: 40s.

case 2:
server->client
ipfs get: 6m32.138s
scp: 2m32.684s

In both cases there are only two peers in the network.

Why so slow?

[Stebalien]

We are aware that transfering files directly between two peers on a fast network is slower than directly copying the files and we're working on fixing the underlying components responsible.

I've written up a meta-issue to explain what's going on and track progress on fixes: #6599
