Poor performance when deleting files (IOPS?)

Good morning

I have noticed some weird performance issues while deleting multiple files. This only happens when deleting files. I can do mass-renaming of files at far higher speeds (IOPS).

One example: Deleting 200 files see speeds drop towards 1 file/s in Windows 10 (SMB share). Is this normal, or some sort of issue, and if it is, is it client based (my Windows 10 desktop), or server based?

HW:
MB: X9SRL-F
CPU: E5-2650 v2
RAM: 64GB (48GB dedicated to freeNAS, 16GB to a VM in freeNAS)
HBAs: 2x LSI 9211-8i in IT-mode
Main (and only) pool: 10x10TB WD Red White Labels
NIC: Intel X540-T2

Have you tried using the ixnas VFS object and removing zfsacl and zfs_space objects?

You should look for the threads/resources from @anodos to make your SMB shares work their best.

I'm dont know what this is, so no, I havent tried it hah. But I will look into it, and try. I guess this might be covered in anodos' threads?

If you go into the settings of your SMB share, you will see the VFS objects there at the bottom when you have turned on Advanced Mode.

You should find information about that in the threads and resources too.
