Yesterday I had a training from Spyro Papademetriou from Orbital Data. I now know all there is to know about accelerating Wide Area Network's using the Orbital appliances.
It's tremendous what they can do in optimizing your connection. Up to 4600 times faster connections. At first I didn't quite believe it, but now, understanding the underlying technology and having seen the demo: I'm a believer!
The demo showed a 4MB powerpoint taking about 3 minutes (=180 seconds) to download from the States to the Netherlands over a WiFi connection in the conference area. Using the Orbital appliance it went down to about 15 seconds. After changing the powerpoint and the uploading of the same file back to the server only took 9 seconds. Cool!
