@Skyismilkingus given Sky Briadband use the same connection as most other ISPs the speed delivered to your Sky hub will be the same as if you bought from BT or who ever. You can check that by running the Sevice Checker in the My Sky app if there is an issue then the app should offer support.
Where many people hit issues is with WiFi speeds in their homes which you can check by running a test using axsite like Fast.com. WiFi speeds will vary due to the layout if your home and Sky's hubs are not the best performers.
However speed, or more properly bandwidth, is not everything you can double connection speed and find a page still takes the sametime to load as the server still has to respond and your browser still needs time to render the page. Use of security suites also can slow down browsing as they check the data .
