Anfang 2026 wurde ein erneuter Bericht \u00fcber das Problem eingereicht, in dessen Verlauf der unabh\u00e4ngige Entwickler ValdikSS eine detaillierte Profilierung mit isolierten cgroup- und Loop-Ger\u00e4ten durchf\u00fchrte, die den Mechanismus der Problemverursachung eindrucksvoll belegte: Aufgrund der Verwendung von in den Speicher abgebildeten Dateien (mmap) und bin\u00e4ren Hash-Tabellen f\u00fchrt das Schreiben selbst einer einzigen Textnachricht von 750 Byte zu \u00c4nderungen an den Abbildungen im Speicher, was zu einem vollst\u00e4ndigen 4-Kilobyte-Seitenabgleich auf der Festplatte f\u00fchrt und von 50 bis 70 KB endg\u00fcltigem I\/O auf Blockger\u00e4tsebene generiert. <\/p>\n

Nach der gestrigen Ver\u00f6ffentlichung des Problemberichts auf der Startseite von Hacker News und der Ver\u00f6ffentlichung unumst\u00f6\u00dflicher synthetischer Tests \u00e4nderten die Macher des Projekts ihre Rhetorik und begannen mit der Optimierung der Mechanismen f\u00fcr das Caching und die Struktur der Speicherung von Journald-Indizes.
