In some cases, the increase in speed may be very limited. Although it depends on a case by case basis the following simple rules may be used to determine the experted increase in execution speed:
- execution time of an individual module <= 1 sec: expected increase < 20%
- execution time of an individual module > 1 sec < 10: expected increase between 20 and 50%
- execution time of an individual module > 10 sec: expected increase > 50 % and < 100 %
The percentage given in the list above should be scaled using the amount of cores used. The 100% in the example above is a two-fold increase using two cores.
Other factors that influence this are the amount of data being retrieved and store in the FEWS database in relation to the total execution time and (in the case of an external module) the amount of data written to and read from the file system.Describe all known issues and unexpected behaviour
