The branch stable/14 has been updated by delphij: URL: https://cgit.FreeBSD.org/src/commit/?id=984caafec11e2b9b044d23dda23a67270f6108ea commit 984caafec11e2b9b044d23dda23a67270f6108ea Author: Xin LI <delphij@FreeBSD.org> AuthorDate: 2024-02-19 23:01:04 +0000 Commit: Xin LI <delphij@FreeBSD.org> CommitDate: 2024-03-21 03:49:04 +0000 zlib: use more memory for a small deflate speedup. The LIT_MEM option uses slightly more memory (for base gzip(1), about 16kiB; according to the author, about 6% for default deflate settings) for a small speedup. The performance gain is more noticeable for input data with higher entropy and less significant for data that is highly compressible, such as source code and logs.
