An obsolete benchmark of computer performance, the first version of which was published in 1984 by Reinhold P. Weicker. It tests how fast the computer can do operations with whole numbers. How many times the dhrystone program will run in one second is divided by 1757, which is the number of times the dhrystone program will run in 1 second on a VAX 11/780, a machine chosen as a benchmark.

The name is a sort of pun. A preexisting benchmark for floating point operations (math with numbers that have a decimal point) was called Whetstone. The opposite of w(h)et is d(h)ry.
