Optimising Ubuntu performance on amd64 architecture

Article Ubuntu

Everyone wants the Linux distribution they are using to be fast. This is practically a content-free statement, of course: who would want their distro to be slow? But at the same time, what does it mean for your distribution to be fast? For example, Ubuntu 21.10 switched the default compression for packages to zstd, which

KDE snaps performance revving up

Article Ubuntu

Speed, or rather, responsiveness is an essential part of the software usage experience. This applies to every technology and domain, snaps included. Indeed, when it comes to snaps, the equation is a bit more complicated and slightly less straightforward because snaps are packaged as compressed, standalone applications...

Article Ubuntu

A great user experience is (or at least, should be) an integral part of any software that involves user interaction. On the desktop, this starts with the application launch, and continues through the session.

Introducing etrace – a multi-purpose application profiling tool

Article Desktop

These days, the internal workings of Linux applications involve many different moving parts. Sometimes, it can be rather difficult to debug them when things go wrong or run slower than expected.

Snap speed improvements with new compression algorithm!

Article Desktop

Security and performance are often mutually exclusive concepts. A great user experience is one that manages to blend the two in a way that does not compromise on robust, solid foundations of security on one hand, and a fast, responsive software interaction on the other. Snaps are self-contained applications, with...
