How does it work? We implement parallel processing. See example below:
 

A single instance of the program processes 10,000,000 rows in 1 hour

Example 1

Running process in parallel means that each shares the work. So if 2 processes are used 10,000,000 rows can be processed in 30 minutes.

Example 2

10,000,000 rows can be processed in 15 minutes if 4 processes are used.
