I've noticed that I get varying download speeds reported, depending on which speed test site I use. These were all taken one after another on a wired connection with WiFi disabled on my router, and with the Internet security package on my laptop disabled:
fast.com - 700 Mbps download, 93 Mbps upload
speedtest.net - 250 Mbps download, 96 Mbps upload
thinkbroadband.com - 237 Mbps download, 93 Mbps upload
checker.ofcom.org.uk - 467 Mbps download, 91 Mbps upload
speedtest.btwholesale.com - 320 Mbps download, 210 Mbps upload
The traffic monitor on my router showed the maximum download speed during the above tests as 638 Mbps.
