Like already mentioned and updated in my previous post Meltdown and Spectre on SPARC we got some patches from Oracle for Solaris:
Oracle Support Document 2349278.1 (Oracle Solaris on SPARC — Spectre (CVE-2017-5753, CVE-2017-5715) and Meltdown (CVE-2017-5754) Vulnerabilities)
Will update some performance impacts if I see them… please share your experiences about performance issues with those patches….
Oracle published a new MOS article about the impact:
Oracle Support Document 2386271.1 (Performance impact of technical mitigation measure against vulnerability CVE-2017-5715 (Spectre v2) on SPARC Servers)
Like on other architectures 2-10% … heard some very bad news from customers using older Intel boxes with up to 70% IO loss… real world examples will be interesting…
