I think 5238 dropped packets for several days compared to received
packets is negligible.

It shows 1Gbit.

Yes. Cables are new cat6e.

I've tried send/receive cifs (samba). Also I've tried sendng file with
pscp using Kitty. Both give same low speed.
NFS or iSCSI isn't used.

70% of 1Gbit. Is this seems a problem with samba?

Disk is a zfs raid:
zpool create -f -m none -o ashift=12 zfspool raidz2 .... (total 8 x 1TB
+ 8 x 2TB disk in SATA2 supermicro backplane)
zfs set atime=off zfspool
zfs set dedup=off zfspool
zfs create -V 4T zfspool/backup
zfs set compression=lz4 zfspool/backup
mkfs.ext4 -b 4096 -q /dev/zvol/zfspool/backup
Is this samba problem or zfs problem?
