RN2120 Extremely Slow Image Load Times
RN2120 is recently having some serious load times with images. This is used for manufacturing to save pictures of products. There is a folder for images created every day. I have 4 x 12tb IronWolfs i...
I used NAS Tester v1.7, 400mb files on 5 iterations. It was just something I found people using to test on the forums here.
I have tried disconnecting one of the network cables, but I can't say I tried it for long. I need to retest this method.
I will pull the log files today and review them for packet loss. And I will replace all the network cables as they may be older than I thought. I am yet to run any sort of maintenance on the volumes. I was uncertain of the best practice for this or the length of time it would take as I only have about 36hours on the weekend of downtime to accomplish this.
So yesterday I removed one of the machines that was uploading images to this NAS and it was still slow. But today it seems to be running perfectly. Before removing this machine I was probably writing 26 images per minute to this NAS. Image files between 3 to 6 mb each. I wonder if it was still slow after disabling one machine that was uploading because the NAS had to catch up?
I am now writing only 10 images between 2.5-4mb each to it per minute and it seems to be running just fine. I am able to lookup images quickly, and I am having no issues writing them. Maybe it was just being loaded down too much?

Great, that's useful, and the results are fairly easily duplicated.

Possibly. The RN2120 has a slower processor than the other rackmounts. It's possible that just rebooting it resolved the problem (perhaps a memory leak or something else was hurting performance).

That could be a problem, though the both the balance and the scrub can be canceled. The scrub time is similar to a resync.
