how to do multiprocessing in java, and what speed gains to expect?

Question

I am a newbie using Java to do some data processing on csv files. For that I use the multithreading capabilities of Java (pools of threads) to batch-import the csv files into Ja

Answer 1

Each developer should have some understanding about Amdahl's law to understand how the multi processing would speed up based on the given conditions.

Amdahl's law is a model for the relationship between the expected speedup of parallelized implementations of an algorithm relative to the serial algorithm, under the assumption that the problem size remains the same when parallelized.
