Hello,
Not sure if this will help,
Approximately 12 months ago I was working for a company as a GIS SDE Administrator, this required a lot of after hours work in both ArcGIS Desktop and Catalogue from home over a VPN, I found it crazy slow,.
The best work around I came up with, although not the most elegant solution, is to RDP in to my workstation in the office (you will need to put a big sticker on it asking people not to turn it off).
I found this works extremely well, because even slow network speeds really don�??t affect the redraw performance because the PC in the office is doing all the work.
Admittedly if you were doing lots of editing it might still be frustrating as there is still a lag, but but if you can swing it RDP into a PC in the office.
Hope this helps
Matt
