Slow file saves for clients

I have a DS6100 for my business. Suddenly we are getting slow file saves for clients saving files on the DS6100.

File saves of any size or type typically took less than one second. Now file saves can take upwards of 30+ seconds and the clients are complaining.

My server has double the default RAM and is running RAID 10. I’ve tried almost anything you can imagine with no success. It is also very difficult to re-create the problem, it is intermittent.

All clients running Windows 10, and Office 2013, with all current updates, they are all on the LAN.

Any thoughts or suggestions?
