Windows Memory Manager To Introduce Compression
jones_supa writes: Even though the RTM version of Windows 10 is already out of the door, Microsoft will keep releasing beta builds of the operating system to Windows Insiders. The first one will be build 10525, which introduces some color personalization options, but also interesting improvements to memory management. A new concept is called a compression store, which is an in-memory collection of compressed pages. When memory pressure gets high enough, stale pages will be compressed instead of swapping them out. The compression store will live in the System process's working set. As usual, Microsoft will be receiving comments on the new features via the Feedback app.
Gee, an Apple product did this in the 90's, compressing memory segments assigned to processes not currently executing.
(see, for example, https://www.usenix.org/legacy/...)
The same product was Apple's first to use pre-emptive multitasking,
The product? Newton.
I vaguely remembered that that (or a similar product) was analyzed and it actually did nothing.
There was code in it, but all that code was bypassed. One imagines that the programmer couldn't get it working but had to ship something - and his bosses couldn't actually tell if the driver DID anything.
The Macintosh version actually did a few things. Mostly to help alleviate Classic Mac OS's piss poor memory management where you had to pre-allocate a contiguous chunk of memory to each process -- manually.
Guys, guys, guys, guys!!!
Come on. Companies can't list new features without being called negatively on it?
It's silly to point out completely different implementations of the same concept as "DONE BEFORE!". Compression is old and has, could and will be used for many different strategies in the future.
New uses for old concepts is an ongoing thing and should not be regarded as non original. By those standards flight was never a big achievement since birds have been flying for millions of years.
