>>> 1000 / ((1024. ** 6) / 3e9 / 86400 / 365)
82.0593593076069
The algorithm is quadratic in the input size. For a Gigabyte of data, that's 1024^6 operations. Dividing that by 3 * 10^9 operations/second (assuming a 3GHz CPU), 86400 (the number of seconds in a day), and 365 (the number of days in a year), we obtain the runtime (in years) assuming that comparing a single byte takes exactly one operation. Dividing 1000 by that number, we get ~82 operations to compare a single byte, and that doesn't look unreasonable. |
