Hi
I know that this is a freeNAS forum. I am using freeBSD 11.2-RELEASE-p3. Compiled kernel to use target mode.
ctladm portlist
sysctl -a
I've exported zvol with sync=disabled to my debian 9 box. Created fs on int and mounted. I can see ~200 MB/s transfers. No more. Link is negotiated at 4 GB. Both cards same qlogic 2460. Same firmware.
I've noticed that some people have / had same issues

Even when I use backend ramdisk to exclude any IO issues, I still have ~200 MB/s
Also posted a thread at freeBSD forums

When I use sync=disabled SYNCHRONIZE CACHE(10) errors go away.
