Wow! Lowering rsize helped a lot! I can get about 4-5MB/s now. I had tried increasing rsize before, but I didn't imagine lowering it would help. Thank you!
I'll mess around with some of the other parameters now to optimize: * rsize set in client mount command * nconnect set in client mount command * num_servers set by nfsd flag on the server * vfs.nfs.iothreads set in the sysctl.conf of the server But I welcome any other suggestions of parameters to tune. -Nathan On Sat, Apr 18, 2020 at 2:55 AM Родин Максим <[email protected]> wrote: > > Hello, > Try these options: > > sudo mount.nfs -o wsize=8192,rsize=8192 IPADDRESS:/shara /home/myuser/shara/ > > Play with wsize and rsize to achieve better speed. > These are mines. > > 18.04.2020 02:31, Nathan Clement пишет: > > Hello, > > > > I am trying to get an Intel atom mini itx board running as an OpenBSD 6.6 > > NAS. > > I've got the necessary daemons running on the mini itx board: > > > >> doas rcctl ls started > > cron > > httpd > > mountd > > nfsd > > ntpd > > pflogd > > portmap > > slaacd > > smtpd > > sndiod > > sshd > > syslogd > > > > and exports is set up: > > > >> cat /etc/exports > > /home/nathan/shared -alldirs -ro > > > > I am mounting this from my laptop which runs on arch linux at the moment. > > On the linux client machine, this is the relevant line from mount: > > > > 192.168.1.4:/home/nathan/shared on /home/nathan/mnt type nfs > > (rw,relatime,vers=3,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.1.4,mountvers=3,mountport=997,mountproto=udp,local_lock=none,addr=192.168.1.4) > > > > I can copy small files over nfs, but anything large takes way too long. > > I've read rsync isn't necessarily the best way to gauge transfer speed, but > > rsync shows I'm getting about 38kB/s transfer speed.
