Optimising Ubuntu performance on amd64 architecture

Ubuntu Article

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 ...

How to make snaps faster

Ubuntu Article

A great user experience is (or at least, should be) an integral part of any software that involves user interaction.

Introducing etrace – a multi-purpose application profiling tool

Desktop Article

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!

Desktop Article

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.
