Jumbo or not Jumbo


Do we get any performance improvement using Jumbo frames?

Enable/disable jumbo frames, using link aggregation and other tricks don’t help at all to improve write/read performance so far… 


on my networks with mostly Mac’s I get terrible performance w/ Jumbo frames. 

With PC on my network I get no real improvement.  I turned it off. 

What’s weird, is Mac to Mac over SMB2 protocol and I get full Gb at over 100 MB/s transfer speed

SMB2 protocol is enabled on my EX4 which supports automatic sizing of packets and it’s still a dog.  Chalking it up to bad software on the EX4 ( again )

I enabled SMB2 and still no improvements so far.
