Typical example is when shutting down a memoryintensive application. It can take quite a while before the computer gets back up to speed. Is there some inherent cost in releasing memory? Or is it throttled by some kind of harddrive activity, and if so is there any good way to track that?
I usually bring up task manager when a computer is running slow, and usually sorting by cpu activity can show what process is causing the problem, but sometimes there is no activity showing. And yes I "show processes from all users", I have been wondering this since the days win2k :)
Hardware issue is a possibility. HDD issue is likely. Memory issue is also likely but more often causing a BSOD rather than just a froze, and keep going. – Darius – 2013-10-23T14:29:30.437
5It's probably all the memory book-keeping. Pages have to be deallocated from both the page table and page file, on top of any files that have to be saved to disk. What does disk activity look like while the application is closing? Does the HDD hit 100% utilization? – Darth Android – 2013-10-23T14:31:29.407
The point of the question was to be rather broad, and it was excellently answered below, so I would not call it too broad! – Joakim Tall – 2013-10-24T15:00:07.973
@DarthAndroid I'm not that familiar with the page terms but I guess thats basically the same advice as in the answer below? I'll learn to look for HDD activity to read my system better – Joakim Tall – 2013-10-24T15:01:34.713
