The creation of custom renditions on-the-fly can be a major problem, especially when it is operating on large asserts. It can lead to high memory consumption, leading to massive garbage collection and even to service outages, when the JVM is throwing an OutOfMemory exception.

For that reason it is recommended to have all required dimensions as renditions (using processing profiles). In that case the AdaptiveImageServlet does not need to resize the image, but just delivers an existing rendition.

To identify such cases there should be a WARN message whenever the AdaptiveImageServlet resizes an image on-the-fly, it should be similar to this one: Adobe-Consulting-Services/acs-aem-commons#3097
