Rising memory usage

Hi @gekomees

The process is single-threaded, it uses a single request per image, so it can’t “accumulate” memory like a long-running process might.

However, the OS might look like it uses up more memory if it doesn’t release it right away. Linux, for example, often looks like it is using more memory than it actually is as it caches things in memory until it needs the memory for something else.

That having been said, any image optimization generally is going to take up a good amount of memory, especially with larger images. 2-4GB of memory is not unheard of when it comes to image manipulation for very large images.
