Extremely Slow File Transfer Speeds

I recently installed an instance of Nexcloud and I am seeing extremely slow file transfer speeds. And when I say slow, I mean slow. Less then 1MB/s. I have searched and have not been able to find a solution.

Nextcloud is being hosted on a local Proxmox vm running Debian 10. We have 4 CPU’s allocated along with 6GB of memory. The data folder is located on a FreeNas hosted NSF share mounted on the Nextcloud VM. We are running Apache and the web server and PHP 7.3

I have done my best to attempt to resolve the issue but I have come up empty handed. I am fairly new to Nextcloud and Linux so my knowledge. Any assistance in diagnosing the problem would be greatly appreciated.
