Plex buffering issues

Server Version#: 1.13.5.5332 (Windows Server 2016 Datacenter)
Player Version#: 3.65.1 (Windows 10 Pro)

Hey all, so I have an up-to-date Plex server with Windows Server 2016 Datacenter Gen2 installed. It has 72GB of RAM (~50GB of which is being used as a cache system with PrimoCache), 2x Xeon E5620 CPU’s, and a bridged NIC (I have tried with and without bridged NIC’s and the bridged one has the least buffering time). The server is DMZ’ed from the outside and the ports are forwarded. Firewall is allowing Plex and all its services to send and receive data on the server and the client. This issue happens across multiple clients and hasn’t happened before on previous Plex servers on my network. Transcoding is set to “Prefer higher speed encoding”. No GPU acceleration is being used due to no GPU being installed.

If this is an issue with Windows, I will gladly switch to a Linux distro but I just want to make sure that it isn’t something I have done to mess with the configuration before I make the switch to the Linux distro and have the same issues. Any help is much appreciated.
