It's not the computer at fault, it's your connection.
Well it's actually both. This computer has only a 1 GHz processor, which could be considered fast but certainly not compared to today's standards. There's also only 768 MB of RAM in this machine, and a rather low amount of harddrive space. My PC is 2.2 GHz, more memory and hard drive space, and I think I have a higher connection speed there.
