Slow Sockets on Mac

[Ralph DiMola]

I'm transferring 40mb over sockets a chunk at a time. The receiver is on a Win 10 Pro Hyper-V Host using LC 8.2.1. The sender uses LC 8.2.1 also.
Sender on a Win10 Host==> 10 seconds
Sender on a Win10 Pro VM==> 10 seconds
Sender on a Win10 Home VM==> 10 seconds
Sender on a 64 bit Linux VM==> 10 seconds
Sender on a Win XP PC==> 10 seconds
Sender on MacBook Pro OS X 10.11==> 60 seconds.

All(except the VMs) have 1000mb nics connected via a 1000mb switch. An increase of 600% makes me think I'm missing something. Anyone else seen this?

Thanks!
