On that note - My N810 (and also DT360) load up and execute commands much slower than what I see in that video. Not to hijack your thread - but, were there any modifications made to achieve that performance? What does the wireless network setup look like? I just have your average off-the-shelf WiFi router running as an AP with WPA-PSK - maybe I have high packet-loss, I haven't checked...
The orbiter on the N810 is the only application that I notice slows down as you load more and more applications, my second N810 is getting too slow to use as an Orbiter now.
Try closing down a few applications on the N810, and disable all the desktop applets.
Also look in N810 Control Panel / Memory / Virtual Tab - tick the box to extend virtual memory, and max it out at 128MB - IIRC this needs you to have a storage card inserted and available.
Wireless is wireless G to a Cisco Access Point - I do notice better throughput with the Cisco box rather than consumer kit, but thats more for large file transfers than the orbiters. Use the Cisco more for it being reliable and never needing to be rebooted.
My WebDT366's respond about as quick as the N810 in the video, so maybe its your server rather than network. Mine is pretty much unstressed as its a dedicated large server in the garage.
Maybe someone more technical can chip in with the architecture, but do you have a load of orbiters that all need to update? I have the two N810's and two DT366's.
