SLOW server in read samba and afp :(

[LUIGIVALTULINI]

hello ,
I built this server:
x9 supermicro dual e5 v2 xeon 8 core total 16 without HT.
128 gb ram ecc.
1 chelsio t520 dual 10gbe and intel 540t2
36 hd 3tb seagate in 12 vdev / raidz
Lsi hba 6g sas dual channel

installed the 11.1 then the 11.2 beta, everything is recognized perfectly without problems.
I have this problem both in samba and in afp , the writing from pc to server of files is very fast saturate the 10gbe 1000mb / s + -, but when it comes to bring files from server to pc or mac is very slow + - 170mb / s. Both in samba and in Afp.
the settings of the network cards are all on Mtu 9000.
do you have any idea? I do not know what to try.
I changed network card, I tried to make a pool other than 4vdev in raidz1 ...
I plugged the Mac and PC directly to the network cards, bypassing the swithc, but nothing.

thank you

Disable the MTU 9000. Run a DD benchmark and report back. Try something like:
dd if=/dev/zero of=/mnt/{POOLNAME}/testfile bs=4M count=10000
and
dd if=/mnt/{POOLNAME}/testfile of=/dev/null bs=4M count=10000
Don't forget to cleanup when done!
rm /mnt/{POOLNAME}/testfile

thanks for your help :)
this:

[root@CINE5K ~]# dd if=/dev/zero of=/mnt/INTERSTELLAR1/testfile bs=4M count=10000

Ahh I forgot to say you need to turn compression off for you pool during the test. Sorry about that. Also use code tags when posting console output. Sorry about that.

1.62GB write & 2.56GB read. not bad. Keep in mind the read speed is augmented by the ARC. When youtesting are you using one big file? Have you tried FTP or similar? I'll admit I'm no AFP or SMB expert.

the files are big and small, can go from 1 GB to 100 GB. I would like to use this NAS for video editing connected to PC and MAc.
If loading material is very fast but as soon as I have to download everything is very slow, strange I should do other tests with iperf maybe.

That may be helpful but I suspect the issue is elsewhere.
