Define max number of transform instances when uploading images

[nettania]

If I upload images using the webinterface, multiple processes of the transform user are initiated to create the thumbnails. Is there a possbility to limit the max number of transform processes to ensure that the server ram is not exceeded if someone upload hundrest of images?

You can see the problem in the attached image. I have uploaded 800 photos in my test environment, and when I watched the images more than 10 convert processes are initiated by Alfresco share(?). Without limitation of the max number of simultanious transform porcesses, it can't scale.

Thanks,

Florian

You can use following properties to limit the simultaneous transforming processes for transform-core-aio:

    transform-core-aio:
        image: docker.io/alfresco/alfresco-transform-core-aio:4.0.0
        environment:
            JAVA_OPTS: >-
              -Dserver.tomcat.threads.max=12
              -Dserver.tomcat.threads.min=4
