Latency using Thunderbolt Ethernet in MAC Book Pro late 2013
Posted on 2014-01-28
I have a MacBook Pro Late 2013 edition. I am using an Apple Thunderbolt to Ethernet adapter and I have also used a Belking Thunderbolt Docking Station with Ethernet and USB 3.0 ports.
When I use the ethernet adapters I am noticing some performance issues. If I start a ping to another device for example, I get 20 replies followed by 5 "request timed out". then I get 20 more replies and 5 "requests timed out". This repeats ad infinitum.
When using software such as Microsoft RDP, the RDP session will freeze for about 5 seconds and then work for about 3 minutes. Then freeze again and so on.
The problem is restricted to the MacBook pro only, and only when using the Thunderbolt dongle or docking station. All other devices on the network do not have the issue. We are using Brocade Datacenter switches which have 1gb/10gb ports.
It happens with both adapters so it doesn't appear to be a problem with just the Apple adapter. I have tried changing priorities of the network cards and still see the problem.
