OK, here is what I have:
If I use Remote Desktop, and run AC client on the server, it is very fast. My benchmark patient opens a lab in 4 seconds, and about the same to close a lab and reload all imported items.
Over the wired network, it is 16 seconds
Over Wireless, about 18 seconds.
The 16 vs. 18 second difference is not enough to make me abandon the convenience of wireless and consider adding the cost of wiring all the exam rooms, but it seems the whole network is really slow by comparison with running the program on the server itself. I would consider wiring the rooms if the wired network We have all the usual; gigabit managed switch, cat 6 cable, etc. So, I think I need to get my IT guys to try and figure out what our true network speed really is.
That still leaves open the question: what is the program doing if it is dragging all that information back and forth over the network? It is tempting to use Remote Desktop and just run it on the server.
