10GbE woes on OSX

[Philipp Meier]

I’m not sure how this conversation got into a discussion about network turnkey solutions when the question was a very basic problem about OS X slowing down 10Gbe connections after a while. I actually believe this to be a bug in OS X as we are too experiencing random slow downs on 10GBe adapters. This has nothing to do with the server or NAS connected on the other side. It’s about the client side.

I had a hunch that it had something to do with 10Gbe over thunderbolt but it seems as if Chris is also experiencing this with regular PCI cards.

Chris, have you made any further discoveries since December? It would be nice to get to the bottom of this and report the issues to Apple.

Bumping this topic up, because I am facing the exact same problem in our edit suite. Mac Pro Late 2013 connecting to a Windows 2012 R2 server over 10GbE with the Sonnet Twin 10G TBL2 Adapter. Speeds are great but will randomly drop to miserable lows after a short time. Lower than 1G even.
Only thing to solve this is to restart the Sonnet adapter, what will bring the connection back up to speed. It will however lose speed pretty much after a couple of minutes again. Very frustrating, especially when you are not a networking pro…

call sonnet
ask for the previous generation of driver for this card. It’s not on the website.
