Since the MBA is capable of significantly greater bandwidth when attached to the 27" Thunderbolt Display, I am wondering if it does, or it's possible to turn on Jumbo Frames?!
If so, how?
For those wondering one day. It is infact available when connecting the Thunderbolt Display to a MBA and a jumbo-frames-enabled network.
Although looking at the performance, doesn't seem to be the full 9000 bytes. Further testing is needed.
