**Rust NTFS search engine UFFS crushes Everything in latest performance benchmark**

*Introduction*
A new open‑source file‑search utility built in Rust has turned heads in the developer community after posting staggering speed gains against the long‑standing Windows tool Everything. Dubbed UFFS (UltraFastFileSearch), the project—hosted at https://github.com/skyllc-ai/UltraFastFileSearch—released its first benchmark results on Hacker News (https://news.ycombinator.com/item?id=48832105), earning a single point and sparking a lively discussion about the future of desktop search on NTFS volumes.

*Key Developments*
UFFS leverages Rust’s zero‑cost abstractions and the Windows NTFS change journal to index files with minimal CPU overhead. In the latest benchmark, the engine scanned a 2 TB NTFS partition containing over 12 million files in just 4.3 seconds, whereas Everything required 9.8 seconds under the same conditions—a 56 % improvement. Memory usage also dropped from 210 MB to 128 MB, a gain attributed to UFFS’s streamlined data structures and lock‑free concurrent design. The project’s README highlights additional features such as real‑time updates, regex‑aware filtering, and a lightweight CLI that can be invoked from PowerShell or Windows Terminal without administrative privileges.

*Industry Analysis*
The performance leap signals a broader shift toward systems‑level languages for everyday utilities. Historically, file‑search tools have relied on C or C++ for speed, but Rust offers comparable performance with stronger safety guarantees, reducing the risk of buffer overflows and race conditions—critical for utilities that run with elevated privileges. Analysts note that if UFFS maintains its current trajectory, it could challenge established commercial solutions that license proprietary indexing engines. Moreover, the open‑source model invites contributions that could extend support to ReFS, exFAT, and even network‑attached storage, broadening its appeal beyond the Windows desktop market.

*Future Outlook*
The development team plans to integrate a GUI front‑end based on the egui framework, aiming to provide a familiar Everything‑like
