To be honest, I've had the best luck with microsoft terminal services in so far as the thin client area goes - I use my XO day to day with my school's remote desktop server and it works flawlessly - the fonts are a bit tiny, but it works with no noticeable speed difference between it and a desktop. Why wasn't this approach considered instead of putting XP on XOs? <div class="gmail_quote">On Sat, Nov 22, 2008 at 7:58 PM, James Cameron <<a href="mailto:quozl@laptop.org">quozl@laptop.org</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="Ih2E3d">On Sat, Nov 22, 2008 at 08:52:12PM +0530, Arjun Sarwal wrote: > I was wondering if someone could comment on the performance when I > have about 30 X0s connected to the same ? </div>Maybe a refresh once every 15 seconds? I've just tried this.  Ran x11vnc -viewonly -shared -forever on a Debian desktop, 1600x1200, and used krdc on a couple of XOs.  In high quality mode, krdc repaints took up to two seconds when a major screen change happened.  But in low quality mode the repaint was about a fifth of a second.  So I have not reproduced your "once about every one second". You are using point to point networking.  As long as the bandwidth of the shared medium (the RF) is not hit, then it should continue to scale. The bandwidth depends on x11vnc options chosen, and on what changes are made to the teaching image.  There are ways to specify to x11vnc what bandwidth to use for the clients.  You should only need to add the right option to ensure you do not fill the RF bandwidth.  See the -speeds option.  4619 lines of man page.  Wow. There's an opportunity here to look for ways to multicast VNC updates. I'm not sure of what is available for this. -- James Cameron    mailto:<a href="mailto:quozl@us.netrek.org">quozl@us.netrek.org</a>     <a href="http://quozl.netrek.org/" target="_blank">http://quozl.netrek.org/</a> _______________________________________________ Devel mailing list <a href="mailto:Devel@lists.laptop.org">Devel@lists.laptop.org</a> <a href="http://lists.laptop.org/listinfo/devel" target="_blank">http://lists.laptop.org/listinfo/devel</a> </blockquote></div> -- Ian Daniher -- OLPC Support Volunteer OLPCinci Repair Center Coordinator -- <a href="mailto:it.daniher@gmail.com">it.daniher@gmail.com</a> Skype : it.daniher <a href="http://irc.freenode.net">irc.freenode.net</a>: Ian_Daniher -- c: 513.290.4942
