Entering folders and files are snappy but i noticed when im looking in a folder filled with pictures 1000+ the thumb nail of the photo takes a while to load.Takes 3 seconds to load ~10.
What can i do to to get my freenas to load the thumbnail faster?
Can this only be solved by extending my pool another 5 disc?(More I/O)
I have seen some threads on the forum talking about editing sync setting and other parameters of the smb service, but it was with a earlier version and said to be default by V11.3.
could mixing hdd speeds negatively impact my read speeds? (4disc 7200rpm 1 5900rpm)
I am using version 11.1U7 and my pool is 2x5TB raidz2
20G ram
lsi9211-i8 I.T.

Is this directory listing performance?
If Samba is single-threaded for most operations could the speed of my cpu be holding something back? (i3-6100)
edit: mangled names = illegal and ea support = false are examples of some of the aux parameters to edit.

Thanks in advance for any suggestions.

What client OS?

Windows (practically?) doesn't use sync writes over SMB. OS X does.

No.

I don't have a good sense of what you should expect for this workload, but I wouldn't be surprised if the files were being loaded by the client one at a time and the thumbnail generated and written back.

i guess just to add to your comment, i have a smb sync app that i sync pictures from my phone to the server. The poor thumbnail performance happens when i view them from my desktop via mapped windows share.

I wouldn't be surprised if the files were being loaded by the client one at a time and the thumbnail generated and written back. could this this be the case even if im using a different client?

Can you explain this thought?

maybe im at a misunderstanding, "files were being loaded by the client one at a time and the thumbnail generated and written back ". If this is the reason for bad performance for thumbnails inside smb, it doesn't make scene to me because my experience deals with a client that doesnt have the files.

I get what you are saying, maybe my issue is due to low I/O, the thumbnail doesnt load fast because the file doesnt load fast.


Is there anyone that has a windows share that loads tiles/icons/thumbnails instantly without having to wait for any loading?

FWIW, my workstation (Windows 10 1903), connected via GbE to my server takes about 3-5 seconds to generate thumbnails for 56 images at 5184x3456 pixels, half in Canon RAW (for low 20s MB apiece) and half in JPEG (at 3-7 MB for most images). The process does seem to do one image at a time.

is your pool a single vdev 6x3TB raidz2?

Yeah, forgot to explicitly mention that.
