In rough order of "speed" improvement *) Remove all backgrounds/wallpapers on the Mac (my wife has her's change every *minute*, with a huge photo fading in all the time -- it's enough to drive me batty). I don't know if ARD has an option to remove the desktop picture, but that's a HUGE help. *) Drop your color to the lowest you can live with. I often times will drop to 256 colors, as that's often about 300% faster than 24 bit color. ;-) You can do this in the viewer or the server, but you'll annoy the user at the remote mac less if you do it in the viewer. *) Change the encoding. You'll have to fiddle with this a little bit, since a lot depends on the system (a 233MHz iMac is going to have some trouble doing tight encoding as opposed to that shiney new G5). I played around a lot with different encodings to see what was "optimal" (in terms of response time) for my systems (I ran Hextile over a WAN link to an Ultra 1 for a long time, as that was pretty much the best setting). *) Compress your SSH stream. Dunno about IPSEC VPN settings (I just set up IPSec on my OpenBSD machines, so I haven't had time to play with it). In summary: Reduce what you need to send, and find the best way to encode what you do send. :-) Sean _______________________________________________ VNC-List mailing list [email protected] To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
