Backend - Is thumbnail generation a performance pain point ?

[jbpenrath]

Bug Report

Problematic behavior We are currently using easy_thumbnail to generate organization logo and course cover thumbnail on the fly. This means those thumbnails are generated at the first access to the field if thumbnails does not yet exist. In our tests, it appears this process is heavy in term of db access and we wonder if it could be a performance pain point for the app.

We must investigate to confirm/deny this assumption.
