The server is= =E2=80=A6 close to being idle during the transfer. From the btop I only see "intr" and "nfsd: server" subprocess=E2=80=A6 But = both use up to 15% CPU per process. Load is 0.7 Dropped the "sync" option on clients, and added "readahead=3D16". That caus= ed the write to speed up from 6MiB/s to 8MiB/s. Should I consider modifying /boot/loader.conf to add: "vfs.maxbcachebuf=3D1048576" there? It's mentioned in the 14.0 release docs. --=20 You are receiving this mail because: You are the assignee for the bug.=
