    Hi Kyle,

    Can you please tell me a little more about your Server? Which OS is it running and what kind of hardware is it running on? 

    Thanks.

    Oops. I forgot the important stuff.

    Mac Mini 5,1 2.3 GHz i5 and 8 GB RAM running OSX 10.9.3

    Connecting via iPhone, iPad, or MacBook Air has the same lag problem.

    We've noticed this issue on 'headless' Mac machines or machines that do not have an active lcd or monitor attached.

    Apple's remote desktop server uses the graphics adapter to accelerate remote desktop encoding. When the computer is headless (or not attached to an external display), the Mac turns off the graphics adapter which (we think) is the cause of a big performance drop. Unfortunately at this time we don't have a good workaround for this other than making sure a physical display is attached to the Mac. We're still looking into alternatives for this.
