Ubuntu 25.10 Planning To Use Dracut By Default

([Ubuntu] 1 Minute Ago Ubuntu 25.10 + Dracut)

For the past number of months there has been talk in the Ubuntu developer space around replacing initramfs-tools with Dracut for handling initrd generation. While there has been progress in switching to Dracut, they aren't over the finish line yet and not until Ubuntu 25.10 are they planning to use Dracut by default.



AWS Graviton4 96-Core Performance vs. AMD EPYC & Intel Xeon CPUs

([Processors] 1 Minute Ago)

Last week I published some initial benchmarks of the Amazon/AWS Graviton4 processors now available within the EC2 cloud using the new "R8g" instances. That initial comparison was a 64 vCPU comparison of Graviton4 against AMD EPYC and Intel Xeon 64 vCPU AWS instances. In today's article is a look at the 96-core Graviton4 bare metal performance using the "r8g.metal-24xl" AWS instance type. The Graviton4 r8g.metal-24xl performance was then compared in today's article against various bare metal AMD EPYC, Ampere Altra Max, and Intel Xeon processors in the lab at Phoronix.
