Multi Stream Migration over Link Aggregated Bridge

[RickoT]

Greetings!

I have 3 nodes in my setup, all with dedicated quad 1gb nics bonded and bridged. I wanted to know if there was a way to take advantage of the bandwidth during migrations. As of now, I note that when I do a migration, it moves data at an average of 112mb/sec. When I do an iperf between nodes, I get about 990, and I can run multiple instances of iperf and still get 990 when running 2 instances. I wanted to know if there was a way to set up pve so when I (or it automagically) does a migration, it can take advantage of the bandwidth available to it by doing multiple streams for a migration. My assumption is that migrations are a single stream between nodes. Is that accurate? If so is it possible to change this behavior?

Thanks!

but note that likely you are comparing 112Mb/s to 990mbit/s, which is almost equivalent, so the speedup is at most 2x (if no other traffic is flowing and nothing else is the bottle neck!)..
