I have a Windows server with 8GB DDR3 1600Mhz, Core i3 3.5Ghz, 5 Hard Drives and a 430W hard drive.
I primarily watch Plex on a Roku 3 that is hard wired into a network switch (linksys WRT54G in AP mode) the network.
My plex server also operates as a backup server (there is a nightly 8pm rsync backup routine that takes a backup over the internet) AND I also do all of my downloading on the same server... both torrents and usenet.
Sometimes the video lags. I have had a message come up that says the connection is too slow and I have also had a message come up that says something like the server doesn't have enough processing power.
Any ideas? Thanks!
