W10 / Shutdown / Hyberfil.sys
One laptop always needs minutes to shut down if the hyberfil.sys is activated.
This only happens on that laptop. All other machines are shutting down normal. Is there a tool out to log the activities during the shutdown? I want to know who is writing so much data to the hyberfil.sys at shutdown. rgrds |

The OS only hibernates stuff it knows about. It has to back up any memory in use, and ignore memory not in use, during the hibernation process. It doesn't just blindly compress the contents of every memory stick, as that would take too long on average. And while the columns in Task Manager "tell a story", remember that this is Windows and plenty of stuff that matters, "isn't on the map". I run into this all the time, with perfmon.msc behaviors not counting activities on the machine. (You can have disk I/O, and it doesn't show in a graph.) If a driver leaked memory in kernel Ring 0, how would we see that ? Maybe poolmon could see it. I bet the OS does back that up during hibernation, even if the leaked content has no value whatsoever. Some OSes have a paged and unpaged pool indicator in Task Manager. I don't have a magic wand for this question. I would be hard pressed, to figure out every little chunk of memory that is being allocated. If you were running a RAMDisk in regular system memory, then hibernation would be forced to record that. The allocation in Task Manager, would only show in terms of the "Memory Pane" total memory used. Paul |
