SMB/AFP/NFS preformance issue mac

[robojot]

Im running into a wierd issue with FreeNAS-11.0-U4 (54848d13b) and MacOS Clients.
The systems clients are for the most part running MacOS 10.13-10.14, but the same behavior is seen with older systems as well.
Our issue is that file share preformance has roughly half the troughput on read compared to write. Most systems are on 1gb/e and will therefor run at about 110MB/s Write and 50MB/s read with AFP. The same goes for SMB and NFS shares from the same system. The same systems with a 10gb/e fiber interface will easly do a symetrical 850MB/s from the server trough the same exact switches and config with MTU 1500
The system is currently running striped mirrors with 8 drives, ZIL and l2arc. Raw system performance with DD is about 900MB/s

Our system is running a
Intel(R) Xeon(R) CPU E5-2620 v4 with 64GB ram in a Supermicro chassies with a Supermicro HBA and backplane.
System is hooked up to the rest of the with a single SFP+ DAC Cable.

The odd part is that Windows and CentOS systems will pull a even 95MB/s r/w on 1gb/e

Currently SMB shares from the Freenas system is running with these VFS Objects:
zfs_space
zfsacl
streams_xattr
aio_pthread
fruit
catia

Mod note -- snip at user request --

Thanks in advance. Im completely stuck here.

Try reproducing with a recent FreeNAS build.

I have the exact same issue, but on FreeNAS 11.2

VFS Objects: streams_xattr, zfs_space, zfsacl

Only SMB and NFS is halved, AFP has +100MB/s both read/write sustained.

Testing large files only.

I have these Aux parameters set on SMB:

ea support = no
store dos attributes = no
map archive = no
map hidden = no
map readonly = no
map system = no
