I'm in the same boat, I just switched to using it for Kavita, which only does some basic open Image -> Thumbnail to smaller size -> write to disk when importing

  Generally yes, but the wording of "instantly" begs for the following pedantic remark: This is controlled by jemalloc settings `dirty_decay_ms`, `muzzy_decay_ms`, and their interaction with `background_thread`. `dirty_decay_ms` currently defaults to 10 seconds, so it's not that instant. That is important e.g. for single-threaded programs that start other programs, such as my Python example: If it starts a subprocess before the 10 seconds elapse after `free()`, Python (and jemalloc) do not run, and get no chance to return memory to the OS. In such cases, either enable `background_thread`, or set the `_decay_` values to `0` to ensure immediate return to the OS upon `free()`. (This costs some performance.) See e.g. https://github.com/jemalloc/jemalloc/issues/2688 https://github.com/jemalloc/jemalloc/issues/2688
