On the latter point, macOS had had compression memory for a long time by now and some Linux distributions also use it out of the box (I don’t know anything about Windows).
- wongogue 2y agoIt also has Compressed Memory since a version of Windows 10. You can see it in Task Manager.
- hinkley 2y agoOne of the time series databases streams compressed blocks in memory when doing searches, doing distinct blocks per core. For some scenarios it's faster to do a table scan than keep extra indexes hot.
- vardump 2y agoI think the grandparent was talking about transparent memory bus data compression. CPU would fetch some bag of bytes and decompress to cache.
- DaoVeles 2y agoEven in the 90's I recall decompressing ZIP files on a 486 being limited by the HDD speed. It felt like even then we would head towards compressed memory systems once it could be compressed quickly enough.
- Dylan16807 2y agoThat's compression for currently inactive pages, not nearly as aggressive as compressing as a matter of course.
- saagarjha 2y agoThis is basically intended to be fast swap rather than something to be applied to active pages.
