It is possible that stone suitable for use as "whetstones" was found in
that area.
A lot of things have happened in that village:
https://en.wikipedia.org/wiki/Whetstone,_Leicestershire
Whetstone was the site of Frank Whittle's factory, where jet engines
were developed. ... Until 2002 the site still sounded an
air raid siren at 8am once a week on a Wednesday.
The site of the Whittle factory became the English Electric Company
(Later GEC) a significant part of several Nuclear power stations
were made there in the 1960s and 70s. English Electric was one of
the largest Engineering Companies in the Leicester area, employing
thousands of workers and training hundreds of apprentices each year.
At one point more than 4,000 workers had to be shipped in from
Middlesex to help labour shortages and many settled permanently
causing a boom in the late 60s.
The computer performance measurement called the "Whetstone" was
developed by English Electric at the factory and takes its name from
the village.
The "Whetstone" performance measurement got its name from the village
indirectly. The originally performance-measuring program was written in
Algol 60 and compiled using the Whetstone Algol 60 compiler.

>The spelling of Dhrystone is, of course, a joke.
