My building (Victoria Point, Docklands, Melbourne) now has fibre internet provided by Spirit Telecom - I got myself connected the other day on the 50/20 plan. Test results using this program:
Download: 48.90 Mbps
Upload: 12.60 Mbps
which sounds great. But real world experience is not very different from the Optus ADSL I had before (6.6/0.8) - have just done a download of about 70MB and it took the best part of 30 minutes. Any ideas why tester and reality seem so different? I guess you can't suck stuff down a cable any faster than the server can/will deliver.
