Just exchanged 475k of my Doges to Drk all the transactions were instant .
Hi, pleased to meet you. If you want to have a bit of a play with one of darkcoin's wallet features, create a new receiving address as usual, then goto send and tick the instantX in the bottom right hand corner(untick darksend as no anonymous send is required) and use your own address as the recipient. There is a small fee for the instantX but it gets the point across well visually just how powerful the masternodes can be, how many seconds do you make it?
