Here’s Why Ubuntu Linux 20.04 Feels Insanely Fast And Responsive


When Ubuntu 19.10 was released, I wrote that upgrading to it felt like upgrading to a FreeSync or G-Sync display. Something dramatic and borderline magical had happened, but what?
Canonical’s Daniel Van Vugt explained that they started seeking out “cold spots.” Think of a cold spot as Gnome Shell sitting idle for even a few milliseconds when it should be updating the frame being displayed onscreen.
To do this, the team conducted real-time performance analysis using Google Profiler. Combined with Intel’s Mesa driver, they were able to pinpoint where the CPU or GPU had “stalled,” resulting in increased visual latency. You might refer to it as “lag.” And those milliseconds add up.
This led to the zapping of numerous bugs, including one that caused Xorg sessions to be one frame “laggier” than Wayland sessions. Want to read the technical stuff? Click here. Or read Daniel Van Vugt’s complete blog post from last year.

Samsung, Red Hat to Work on Linux Drivers for Future Tech
The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world.
Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility.
