Modern HEDT and server chips\u2014think AMD\u2019s 128-thread Threadripper PRO 7995WX or Intel\u2019s Xeon w9 parts\u2014are split by Windows into multiple \u201cprocessor groups.\u201d Prior releases were capped at a single group, effectively idling excess cores.<\/p>\n\n\n\n<p>Version 25 dynamically distributes its worker threads across all groups, so every logical CPU can lend a hand when packing large zip, 7z or xz archives, and when running the built-in benchmark.<\/p>\n\n\n\n<p>Moreover, speed-ups are now not limited to mega-core rigs. The bzip2 codec now processes data 15\u201340<span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\"><strong>%<\/strong><\/span> faster, while classic deflate (used in .zip and .gz files) enjoys a\u00a01\u20133% boost.<\/p>\n\n\n\n<p>Beyond raw horsepower, 7-Zip quietly tightens its handling of several legacy formats. Support for ZIP, CcPIO, and FAT archives has been refined, smoothing edge-case extractions that previously required third-party tools.<\/p>\n\n\n\n<p>Finally, the release rolls in unspecified bug fixes and vulnerability patches. Given the two zero-day disclosures that hit the project late last year, regular upgraders will welcome the extra peace of mind.<\/p>\n\n\n\n<p>For more information, <a href=\"https:\/\/github.com\/ip7z\/7zip\/releases\/tag\/25.00\" target=\"_blank\" rel=\"noreferrer noopener\">see the changelog<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The latest 7-Zip release speeds up bzip2 by up to 40%, improves ZIP and FAT archive support, and fixes multiple bugs and security vulnerabilities.<\/p>\n","protected":false},"author":10,"featured_media":176108,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7,5],"tags":[3260,5481,3830],"class_list":["post-176105","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-software","category-news","tag-7-zip","tag-archiver","tag-compress"],"blocksy_meta":[],"_links":{"self":[{"href":"https:\/\/linuxiac.com\/wp-json\/wp\/v2\/posts\/176105","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/linuxiac.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/linuxiac.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/linuxiac.com\/wp-json\/wp\/v2\/users\/10"}],"replies":[{"embeddable":true,"href":"https:\/\/linuxiac.com\/wp-json\/wp\/v2\/comments?post=176105"}],"version-history":[{"count":0,"href":"https:\/\/linuxiac.com\/wp-json\/wp\/v2\/posts\/176105\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/linuxiac.com\/wp-json\/wp\/v2\/media\/176108"}],"wp:attachment":[{"href":"https:\/\/linuxiac.com\/wp-json\/wp\/v2\/media?parent=176105"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/linuxiac.com\/wp-json\/wp\/v2\/categories?post=176105"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/linuxiac.com\/wp-json\/wp\/v2\/tags?post=176105"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
