https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230260 --- Comment #7 from commit-hook@freebsd.org --- A commit references this bug: Author: cem Date: Thu Aug 2 19:25:43 UTC 2018 New revision: 337165 URL: https://svnweb.freebsd.org/changeset/base/337165 Log: FUSE: Bump maximum IO size to enable more performant operation Various components restrict size of IO passed up to the userspace filesys= tem based on the mount's f_iosize value. The previous default of PAGE_SIZE is anemic, even for normal filesystems, but especially considering every FUSE operation involves a kernel <-> userspace IPC upcall. Bump to DFLTPHYS (currently 64kB) to match other FUSE implementations. Anecdotally, Jakub reports IO read performance increased from 600 MB/s -> 2700 MB/s with a basic RAM-backed FUSE filesystem.
