I have strange behaviour while using Futuro S920 / release 7.1 as an nfs client. I have two nfsd servers in my lan: FreeBSD 13.1 with ZFS and for comparsion purposes similar Futuro s920 running release 7.1. I tested many mount options and as the most transfer-effective (and usable at all) option I have (mount output):
SERVERIP:/exportedshare on /clientmountpoint type nfs (noatime, nodev, noexec, nosuid, v3, tcp, intr, wsize=1024, rsize=32768, rdirsize=32768, timeo=100, retrans=101, readahead=0) With such config I can reach read speeds at 32 mB/s which is comparable to internal transfers between two SDDs inside the Futuro. But write speed is around 10 times slower no matter if I write to OpenBSD nfs server or FreeBSD. I also tried wsize=32768, no visible change. As for now I did not found any way to reach higher write speeds. While writting multiple small files everything goes slow but smooth, writting file bigger than around 18 megabytes I have lags in the middle and at the end of the transfer process. Depending on the file size it can be few seconds or even more than a minute to finish the whole process, not including random iddles and rebirths. I tested it with Midnight Commander (progress meter showing speed) and also with rsync --progress --stats: both ways look similar. I allready tried to set MTU = 9000 on both ends of communication with also no visible effect. Same with different NIC's - no change. Finally I tried to use other PC machine with Debian Linux as client, and writes/reads with FreeBSD server works like a charm, but communication with the above mentioned second Futuro/OpenBSD has the same write speed issues. I suppose it is some kind of hardware issue at the Futuro side, looks like "some kind" of "write buffer" is overflowing while the sending file size exceeds 18 MB. No idea what can I do to solve my problem, any suggestion appreciated. Below is dmesg from client Futuro: OpenBSD 7.1 (GENERIC.MP) #1: Tue May 3 09:11:23 MDT 2022 r...@syspatch-71-amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/ GENERIC.MP real mem = 3916890112
