Yes, that is my experience too on Linux. However, most times it isn’t actually necessary to write the full RAM out and IIRC Windows and macOS actually don’t. Th

Yes, that is my experience too on Linux. However, most times it isn’t actually necessary to write the full RAM out and IIRC Windows and macOS actually don’t. There are a few approaches that work, e.g. you can do memory ballooning and drop caches to reduce memory usage before suspending. In addition, you can write unused RAM pages to disk during normal operation, so that when the user wants to suspend, most of the pages are already on disk.
