I am installing a new server and workstations at a site. When this is done, all of the computers and switches will be able to handle Jumbo Frames, but the printers, router, and other devices will not. There are also some machines connected via a VPN. Most files are small to medium in size, and file transfer bottlenecks will affect productivity.
I find a lot of differing opinions on whether Jumbo Frames should be enabled. Everything from it will speed things up to it won't make a difference to it will cause applications to not work right, especially across the VPN.
Does anybody know of any authoritative criteria on which to base the decision on whether enabling Jumbo Frames will be beneficial?
