Precision and purpose: Ubuntu 12.04 and the Unity HUD reviewed (ars technica)

[Posted May 31, 2012 by ris]

Ryan Paul takes a look at Unity and the Heads-Up Dispaly (HUD) in the 12.04 release. "The HUD is powered by the same mechanism that supports Unity’s global menu system. In order to make an application’s menus available to Unity so that it can display it in the panel, the contents of the menu are relayed over the D-Bus interprocess communication system. The HUD taps into that data, essentially offering an alternate presentation of the menu. In addition to being extremely useful, the HUD is a compelling illustration of how Unity’s architectural strengths can be put to use in novel ways."

In my experience, using Precise on an Atom (eeePC) is not always a happy experience. In certain conditions, CPU usage goes up for apparently no reason, causing the machine to slow down a lot. One of this cases is when you are in a place with lots of wifi APs, some of which hardly reachable.
Hud appears to be among those processes taking a lot of CPU.
