Multiprocessing takes higher execution time

I use multiprocessing to compare more then one set of files.

For comparison each set of files (i.e. Old file1 Vs New file1) I create a

Process(target=compare, args=(oldFile, newFile)).start()

It takes 61 seconds execution time.


When I do the same comparison without implementing multiprocessing, it takes
52 seconds execution time.


The parallel processing time should be lesser. 


I am not able to get advantage of multiprocessing here.


Any suggestions can be very helpful.
