Canonical has released Ubuntu 24.04 LTS, aka “Noble Numbat,” a new Long Term Support release of the popular Linux distribution that brings performance enhancements and toolchain updates for developers.
Announced April 25 and downloadable from ubuntu.com, Ubuntu 24.04 LTS offers Linux 6.8 kernel capabilities with improved syscall performance, nested KVM (Kernel-based Virtual Machine) support on ppc64el (IBM PowerPC), and access to the new beachefs file system. Ubuntu 24.04 LTS has merged low-latency kernel features into the default kernel, reducing kernel task scheduling delays, Canonical said. The release also enables frame pointers by default on 64-bit architectures, giving performance engineers access to accurate flame graphs when systems are profiled for troubleshooting and optimization. Frame pointers offer more complete CPU profiling and off-CPU profiling, according to Intel.
