Our shared servers are well connected in a major UK data centre - We use Gigabit ethernet connections to the data centres fast network. We used to be able to demonstrate this with a product called Speedtest which we could run on one of our actual hosting servers. Sadly this used Adobe Flash so was outdated and has been replaced by an HTML 5 product below. This will allow you to measure your speed but not to our specific servers. The faster the better but as a minimum you should have 2 Mbps down speed and 0.5 Mbps up speed.
These are a few factors that could slow down your hosted database.
The using styles on WebDirect technique also speeds up Go and Pro
