9 - 10 seconds for me at an average of 480k/sec ( I am 10mb TW in the South Yorkshire area) i downloaded it at 13:50 today .
If you are getting slow speeds then I would recommend rebooting your MODEMS/ROUTERS and trying again. If not try a different website and see what your speeds are like from there. If poor then you have a routing issue and need to report it to your ISP.
