HD4DP Server Requirements from the results of the load testing on acceptance Environments

When installing the new HD4DP application, a reindexation will be performed, this will take more time depending on the number of registrations in the application.
During this reindexation, not all the registrations will be visible. New registrations can still be submitted but won’t be visible in the user interface.
The duration of the reindexation depends heavily on the resources of the machine, therefore we recommend the following specifications for the machine:

  • At least 2 CPU cores, when the machine only runs HD4DP
  • 8 GB RAM, of which 4 GB assigned to the Tomcat server
  • We also recommend running the UM/XConnect on a separate machine

For example in our pre-release tests, a reindexation of 240.000 registrations on a 2 CPU, 4 GB machine could take up to 36 hours. Increasing the RAM to 8 GB reduced this time to 9 hours.
