PCID is now a critical performance/security feature on x86 - On any system that does not currently show 'pcid' in the flags line of /proc/cpuinfo, Meltdown is a bigger issue than 'install latest updates'.Furthermore, testing this feature, particularly when combined with optimizations such as software branch prediction hints, demonstrated that this protection came with almost no performance loss. Google is pushing Retpoline - With Retpoline, we could protect our infrastructure at compile-time, with no source-code modifications.AWS Developer Forums: Degraded performance - Immediately following the reboot my server running on this instance started to suffer from cpu stress.With haste to work around an intel hardware bug. Others), will include new feature that apparently has been implemented heads up: Fix for intel hardware bug will lead to performance regressions - Upcoming versions of the linux kernel (and apparently also windows and.It looks like Dragonfly BSD has a patch, so hopefully that will be useful for FreeBSD. FreeBSD was made aware of Meltdown and Spectre in late December.

In order to make the process more efficient, they started a Slack channel with CEOs, CTOs and engineers from the various companies sharing information and fixes as they became available. How Tier 2 cloud vendors banded together to cope with Spectre and Meltdown | TechCrunch - Eventually six cloud providers - Scaleway, DigitalOcean, Packet, Vultr, Linode and OVH - formed a consortium of sorts to help one another and share information.This post will be updated! If you want to add/correct something, please comment. My version of the timeline on Spectre Meltdown. How we got to Spectre and Meltdown A Timeline My version of the timeline.

Then we run through the timeline of events, and the scuttlebutt of so called coordinated disclosure. Plus a concise breakdown of Meltdown, Spectre, and side-channel attacks like only TechSNAP can. The types of workloads that will see the largest performance impacts from Meltdown, tools to test yourself, and the outlook for 2018.
