When I got started using Drupal 7, I added several fields to my site using the Computed Field module (to calculate age, zodiac sign, and so on).
Now that I have been using Drupal 7 for a few years, I realize that it is generally not a great practice to write PHP code in the UI, as the Computed Field module requires. But, the code I am using has worked for the past few years, so that is no longer an issue.
However, I am wondering if there is a significant performance difference between using the Computed Field module (saving the result in the DB) vs. running the PHP in
hook_node_presave() or in a similar fashion somewhere in a custom module.
Would removing my computed fields (and uninstalling the Computed Field module) and replacing them with fields in a custom module significantly increase performance?
