My network response have became increasingly slow. I have a few web based servers that I run (Plex, iRedMail, Nginx) nothing too heavy really. I have plenty of ram (32GB) and a i7-3770K processor on a Firecuda 7200RPM SSHD drive. I've done I/O tests and it can read and write hundreds of MB's/s and I've done network speed tests with Speedtest cli it has no issues there at 500mbps+, but when I attempt to load anything direct (bypassing Nginx) it loads very slowly. 3.2MB of data takes over 10s to load on a local network from the server direct (test ran in plex) my plexmediaserver is rendering and throwing the images back in about 10ms but then some images are taking >100ms to come back per my Charles.
Can anyone give me some guidance on what to check? I've checked DNS nameservers, I've tried network configurations and I can't figure it out. I don't really want to have to start all over again, this has to be a configuration issue, its not hardware as I tried external gigabit adapter and had the same issue.
