Btrfs Ready With More Performance Improvements For Linux 7.3: Some ~3x To ~5x Wins
Linux 7.3 brings a batch of Btrfs performance improvements submitted by David Sterba of SUSE. Direct I/O now uses the IOmap bounce buffer instead of falling back to buffered I/O, raising throughput from roughly 50% to about 95% of theoretical maximum. Tracking of inhibited extent buffers switched from XArray to a local LRU list, yielding around 3x gains. Removing a one-jiffy delay in non-SSD mode with multiple logging tasks cut latency and boosted throughput about 5x on a sample workload, and skipping hole detection during full fsync for files with many extents but no holes gives another 5x win. Free-space v1 is now disabled by default in favor of the long-standing free-space v2 default, alongside various bug fixes and locking improvements.
