How long will the execution take after optimization? Does it depend on the number of processor threads (GOMAXPROCS)?

The execution time after optimization depends on many factors: the nature of the task, the efficiency of the algorithm, and hardware resources.

Regarding the GOMAXPROCS parameter in Go, it sets the maximum number of OS threads that can execute Go routines simultaneously. Increasing GOMAXPROCS can speed up execution if the task is well parallelized and there are multiple processor cores.

However, if the task is not parallelizable or limited by resources (e.g., I/O, synchronization), increasing GOMAXPROCS will not provide a significant gain.

Therefore, the execution time after optimization can be significantly reduced if the optimization includes parallelization and proper use of GOMAXPROCS, but the exact time depends on the specific implementation and load.
