If I have a network configured like this:
Switch A 1GB -> Switch B 1GB->10/100MB
So I have 2 GB switches daisy chained to a Sonicwall router into the 10/100MB port. Does the traffic between switch A and B run at 1GB potential speed? Does the fact that the PC sometimes passes traffic out through the Sonicwall somehow modify TCP/IP window sizes which might reduce network efficiency?
Reason I ask is I have a client with this setup getting about 30Mbp/s transfer speeds going from pc to pc each with GB nics.
