Linux 6.11 Likely To Land DM-Verity Multi-Buffer Hashing For Big Speed Boost
One of several nice Linux performance optimizations recently by Eric Biggers of Google has been speeding up DM-Verity via multi-buffer hashing
One of several nice Linux performance optimizations recently by Eric Biggers of Google has been speeding up DM-Verity via multi-buffer hashing. DM-Verity is used for transparent integrity checking of block devices and this multi-buffer hashing code looks like it will land with the upcoming Linux 6.11 cycle. The increase in overall throughput of cold-cache dm-verity reads that I'm seeing on arm64 and x86_64 is roughly 35% (though this metric is hard to measure as it jumps around a lot).
