I appreciate the effort, but I don't think that I am being clear enough, so please let me try to restate the problem.

(1) We all agree that when you reboot the N9, there is 255 MB of swap available out of a total swap size of 255 MB. In short, 100% of the swap memory is available immediately after reboot.

(2) I think we all agree that after using the device, the swap memory begins to be consumed, so after a bunch of multitasking, use of heavy apps, etc., the swap memory will drop to something like 200MB out of 255MB total. After more use, it may drop to 130 MB out of 255MB total. And ultimately can reach 0MB out of 255MB total.

(3) On my device, shutting down the heavy apps, multitasking windows, etc. does NOT restore the swap capacity, so the available swap memory tends only to go down.

(4) I have noticed that slowdown both within apps like Fenix and while switching between the three homescreens, and in general other usage, is noticeable and irritating. The slowdown I experience is directly proportional to the degree that swap memory is utilized. Performance slows early on, though it is hardly noticeable, but then gets progressively worse until it absolutely cripples the device.

(5) MY QUESTION. Yes, we all know that rebooting the device will get us back to a snappy 255MB out of 255MB of swap available. BUT, how can this exact result be obtained without rebooting the device??? Something like a swap memory refresh script is what I'm looking for. Can you dig it?
