Guilty. Blame it on oldtimers. > What're the make/models (and most importantly, AGE!) of said switches? They are a Netgear GS-108 for the managed one, about 4 years old, and another unmanaged Netgear GS something, its up on a shelf and mostly out of sight in the garage and its close to a decade old as it started life here, and got moved to the garage when I bought this one. Might be both will handle ipv6, but any ipv6 connectivity stops at the cable modem so I generally keep it disabled. > > > But file moves to/from the machines in the garage seems to indicate > > theres a slow connection of around 10Mb/s someplace in that path. > > What're the two endpoint machines? > Do they both show link state at 1 gbit?

That leaves the write speeds of the SSD's on the other end. And I can't fix that. So lets close this thread.
