Yeah I don't know where this guy is coming from, but their set up must have been provisioned in a deliberately suboptimal way or criminally oversubscribed. Unless you're gaming or expecting scrolling at a rock solid 75 HZ+ refresh current gen RDP is almost indistinguishable from running a local desktop over an internal gigabit link.

Even even over a paltry 15mbit consumer grade cable internet uplink it is possible to play full screen YouTube videos in high def over plain vanilla RDP version 8, without even getting into any of the (often quite flaky and at this point highly redundant) Citrix enhancements.
