A 1GB file will take approximately 15 minutes to download with a 10mbit/s download connection. Typical Ravenscroft 275 download times for most broadband internet users will be around an hour. If you're experiencing a slow download and feel it should be faster, test your speed with any popular online speed test (speedtest.net is a good one).
