I’ve recently upgraded my home connection to Gigabit fiber (1000 mbps down /500 mbps up) and, since I now have 500 mbps of upload bandwidth, I’ve set up a new server.

Since this server has faster upstream connection that that of Raspis, I’ll probably move some of my stuff from Raspis to this new server in near future.

Server specs for those interested:
CPU: Intel G4600
RAM: 4 GB DDR4
NIC: 3x Realtek Gigabit NICs (separate NICs for Router, Internet and IPTV)
Storage: 6 HDDs, approx 3.33 TB of storage.

EDIT: Speedtest (that’s with IPTV and some other stuff running).
