https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276299 --- Comment #3 from dmilith <dmilith@me.com> --- (In reply to Vladimir Druzenko from comment #2) >From the server: vfs.nfsd.srvmaxio: 1048576 vfs.nfsd.maxthreads: 64 I've tried with 128 threads before, but that changed nothing. The server is… close to being idle during the transfer. >From the btop I only see "intr" and "nfsd: server" subprocess… But both use up to 15% CPU per process. Load is 0.7 Dropped the "sync" option on clients, and added "readahead=16". That caused the write to speed up from 6MiB/s to 8MiB/s. Should I consider modifying /boot/loader.conf to add: "vfs.maxbcachebuf=1048576" there? It's mentioned in the 14.0 release docs. -- You are receiving this mail because: You are the assignee for the bug.home | help
