The branch main has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=089eafaff3ec632e1fc56db35dc3b30214c9e5f9 commit 089eafaff3ec632e1fc56db35dc3b30214c9e5f9 Author: Mark Johnston <markj@FreeBSD.org> AuthorDate: 2021-01-20 01:34:35 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2021-01-20 01:34:35 +0000 arm64: Stop setting VM_BCACHE_SIZE_MAX This setting places a (small) limit on the size of the buffer cache, constraining UFS performance on large servers. The setting comes from the initial arm64 implementation and appears to be vestigal. Remove it. Reviewed by: kib Submitted by: Klara, Inc.
