An ambitious Linux developer has successfully executed some adjustments to Linux that provide a 6% improvement in file system performance.
This is described in more detail on X (previously known as Twitter), where Jens Axboe enacted only a few alterations to a caching algorithm that led to a significant acceleration in I/O operations.
Interestingly, Axboe has intended to implement this code modification for a long time, but only recently found the opportunity to do so.
Ultimately, the total work consists of two patches and approximately five minutes of effort, a commendable feat as reported by Phoronix.com, who spotted this tweet.
Moreover, the gains could be bigger on a full-scale distro-style kernel config. Axboe points out: “Results in patch 2, but tldr is a more than 6% improvement (108M -> 115M IOPS) for my test case, which doesn’t even enable most of the costly block layer items that you’d typically find in a distro and which would further increase the number of issue side time calls.”
With any luck, this work will be incorporated into Linux v6.9 and users will get the benefit (that version is expected to arrive as stable in the summer, though we have v6.8 which is close to release before that).
In other recent Linux news, the operating system is going from strength to strength in terms of market share of late. It’s now on 3.82% of desktop PCs out there according to Statcounter’s latest figures for December 2023.
Around the middle of last year, Linux hit fresh heights of 3% market adoption for desktop operating systems, and that momentum has been sustained. Now, we’re looking at the 4% mark, although of course, that’s still a relatively modest total compared to Windows (73%) and macOS (16%).
