I have a late 2013 Macbook Pro Retina (10.10.2) hooked up with a CalDigit TS2 hub using a brand new Apple Thunderbolt 2M cable. I have the hub hooked up to a gigabit switch and I noticed I wasn't getting gigabit speed on a file transfer. I unplugged everything from the CalDigit hub except for the gigabit LAN connection and reran the test with the same results.
When I connect to the gigabit switch with my Thunderbolt to gigabit ethernet adapter with the same ethernet Cat 6 cable, I'm getting around 30% more throughput. I tested rsync to a SanDisk Extreme 64GB USB 3.0 connected directly into a USB 3.0 port on the Mac and connected to the front USB 3.0 port on the hub. The source for the rsych was the internal Mac SSD
Direct
sent 1.61G bytes received 70 bytes 103.71M bytes/sec
total size is 1.61G speedup is 1.00
CalDigit TS2 Hub
sent 1.61G bytes received 54 bytes 91.86M bytes/sec
total size is 1.61G speedup is 1.00
Is this typical overhead with Thunderbolt 2 and an external Thunderbolt 2 hub? I have nothing daisy chained with the hub and system report is showing a 20Gbx1 connection to the hub.
