DESCRIPTION:Modern Linux infrastructure is relentlessly benchmarked. Yet mo
 st storage tests share a critical flaw: they measure performance on freshl
 y formatted filesystems.\nReal systems don’t live in “day zero.” The
 y age. Free space fragments. Metadata scatters. Allocation patterns degrad
 e. Subtle regressions often emerge only after months or years of productio
 n churn.\nBy relying on day-zero testing\, we miss performance cliffs that
  surface only in aged environments.\nTo close this gap\, we need practical
  ways to rapidly age a filesystem. In this lightning talk\, I will break d
 own the methods used to simulate years of filesystem fragmentation and wea
 r in just a matter of minutes. Finally\, I will introduce Filestorm\, a fu
 lly working\, production-ready benchmark that encapsulates these rapid-agi
 ng techniques into a single tool\, and share examples of real-world regres
 sions it has already caught in the wild.
