Previously I had Virgin Media and the 600Mbit package, which I was able to fully saturate.

11:33:07 (21.0 MB/s) - '1GB.bin.1' saved Īs we can see, the real world performance against multiple hosts, in multiple data centres, in multiple regions (UK, NL, DE), shows a significantly different picture.Īt those speeds I'm not anywhere near the "minimum guaranteed download speed". Let's repeat the same tests using actual speedtest files over HTTPS, showing real world performance: These are likely conducted fully in memory, on a nice optimised server or CDN to give the best results possible. When running online speedtests, the speed is mostly what I would expect. Running Windows 10 64bit, fully up to date, with an i7-8700k overclocked to 4.9GH/z, 16GB of DDR4 RAM. The disk being wrote to is an NVME SSD PCI-E at x4, read is 2.6GB/s and write is 1.8GB/s. NIC is an Intel Ethernet Connection I219-V, 1Gbit, latest driver installed, tried auto negotiation and 1gbit full duplex, link speed shows as 1gbit on either. The cable is Cat 7a, up to 10gig supported. To rule out the router BT provided as the issue, I've connected the computer directly to the ONT and set up a PPPOE connection. I'm experiencing slower speeds than expected on Full FIbre 900.įTTP was installed several weeks ago, "normal available download speed will be between 900 - 900 Mbps", and the "minimum guaranteed download speed will be 450Mbps".īetween 112.5MB/s and 112.5MB/s (very unlikely), and a minimum guaranteed speed of 56.25MB/s (likely).
