Changes include new KUnit benchmark coverage for XOR and RAID6 code, using a more realistic 4+1 disk load calculation, and reporting throughput on data disks rather than just the parity disk. No benchmark data was provided to quantify the real-world impact of these changes, with the rest of the non-MM pull request consisting mostly of routine bug fixes. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What changes does Linux 7.3 make to RAID 5/6 algorithm selection? Linux 7.3 improves the benchmark-based selection of the RAID XOR engine and RAID6 code paths that Linux runs during kernel module initialization to pick the fastest hardware-accelerated method, such as AVX2 or AVX-512. It adds KUnit benchmark coverage for XOR and RAID6 code, uses a 4+1 disk setup for more realistic load calculation, and reports throughput on data disks instead of just the parity disk. _Track kernel storage changes like this RAID benchmarking update as new Linux releases roll out, via daily.dev._ ## Similar posts on daily.dev - [AVX-512 xor\_gen For Linux Updated & Looking Real Good For RAID Arrays](https://daily.dev/posts/avx-512-xor-gen-for-linux-updated-looking-real-good-for-raid-arrays-s5zaoow00) · Phoronix · 0 upvotes · 0 comments - [Linux 7.4 Slated To Land The AVX-512 Optimized xor\_gen For A Big Performance Win](https://daily.dev/posts/linux-7-4-slated-to-land-the-avx-512-optimized-xor-gen-for-a-big-performance-win-t35igbvrm) · Phoronix · 0 upvotes · 0 comments - [AVX-512 Optimization For Linux RAID Showing Up To 41% Improvement On AMD Ryzen 9 9950X](https://daily.dev/posts/avx-512-optimization-for-linux-raid-showing-up-to-41-improvement-on-amd-ryzen-9-9950x-poo478v4o) · Phoronix · 1 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#performance](https://daily.dev/tags/performance), [#storage](https://daily.dev/tags/storage) [View this post on daily.dev](https://daily.dev/posts/linux-7-3-improving-raid-5-6-benchmark-based-algorithm-selection-fwrdpf5c2) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Linux 7.3 Improving RAID 5/6 Benchmark-Based Algorithm Selection","url":"https://daily.dev/posts/linux-7-3-improving-raid-5-6-benchmark-based-algorithm-selection-fwrdpf5c2","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/linux-7-3-improving-raid-5-6-benchmark-based-algorithm-selection-fwrdpf5c2"},"datePublished":"2026-08-24T00:41:32.203Z","dateModified":"2026-10-15T02:20:24.903Z","description":"Linux 7.3 includes improvements to the benchmark-based algorithm selection used for RAID 5/6 software configurations, refining how the kernel picks the fastest...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/f04a7698cb28370daefdf2244877b082?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/f04a7698cb28370daefdf2244877b082?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Phoronix","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Phoronix","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/6a26ba379dd64932830aa0c9803dd7ee","url":"https://daily.dev/sources/phoronix"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/linux-7-3-improving-raid-5-6-benchmark-based-algorithm-selection-fwrdpf5c2","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux,performance,storage","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Phoronix","item":"https://daily.dev/sources/phoronix"},{"@type":"ListItem","position":3,"name":"Linux 7.3 Improving RAID 5/6 Benchmark-Based Algorithm Selection"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/linux-7-3-improving-raid-5-6-benchmark-based-algorithm-selection-fwrdpf5c2#faq","mainEntity":[{"@type":"Question","name":"What changes does Linux 7.3 make to RAID 5/6 algorithm selection?","acceptedAnswer":{"@type":"Answer","text":"Linux 7.3 improves the benchmark-based selection of the RAID XOR engine and RAID6 code paths that Linux runs during kernel module initialization to pick the fastest hardware-accelerated method, such as AVX2 or AVX-512.
