We'll go through these in basic chronological order, which also happens to be more or less in order of speed, from slowest to fastest, with some exceptions.
De Grasse had ordered the ships to form into a line as they exited the bay, in order of speed and without regard to its normal sailing order.
Quinn notes that this is just the first of many speed initiative Digg has planned for the coming months, and notes that they "will result in order-of-magnitude speed-ups for many use cases".
The measured sweeping velocity is of the order of Alfvén speed (V_{mathrm{A}}) and the sound speed (c_{mathrm{s}}), and is closest to the magnetosonic speed (sqrt{V_{mathrm{A}}^2 + c_{mathrm{s}}^2}).
The spreading speed is of the order of the speed of a gravity current that excludes the influence of thermal expansion.
The magnitude of the relative velocity is related to the effective sound speed of the gas, which is of the order of the speed of light before recombination due to Compton scattering.
The four fastest days to drive in Manhattan, in order of average speed: New Year's Day, Christmas, Memorial Day and July 4. (Thanksgiving Day? Hindered, presumably, by the Macy's parade).
The performance of intermodulation interference system (Intermode60) achieved an order of magnitude speed improvement.
At the high order of engine speed, differences between the computational and experimental results exist in the high revolution range (from 5000 to 6000 rpm at the 4th order, and from 4200 to 6000 rpm at the 6th order).
The order of the speed of the neutral wind at an altitude of 100 km, i.e., the E-layer, caused by the acoustic wave is 10 m/s, and the spatial scale is around 100 km.
