Daniel, thank you!
I did the change in the CPU bios now and run the test again. This are
the results:

1) The processing time for one client decreased to 1:30 minutes (25%
less).
2) Running the system with 4 clients the time continued almost 4
times more (5:20 minutes).
3) Looking at the log for each client we could noticed:
3.1) Although each client started at the same time (we put 4
engineers starting the application at once in each microcomputer) the
second client started 17 seconds after the first, the third started
57 seconds after the second and the fourth 40 seconds after the third.
3.2) It seems that the FB could not start the four clients at once.

Is there something in the FB configuration that we could change to
solve this?
