operation time; computation time
Technical computing term for the time taken to perform a calculation or processing operation.
The operation time of this algorithm is proportional to the input size.
We introduced parallel processing to reduce computation time.
計算時間 is a broader term for calculation time in general, while 演算時間 is more specific to the execution time of an arithmetic or logical operation in computing contexts.
Compound of 演算 (operation, calculation) and 時間 (time). A straightforward technical term.
