Does Windows 10 use memory caching?

Every time I turn on my desktop I let it sit on the desktop for a while. I usually then open 3 apps: SAMP, Groove Music, and Firefox. I've noticed that recently these apps seem to be opening faster and faster every time I use the PC, and just now I opened all 3 of them with literally no delay between releasing my hand off the mouse and the program appearing on screen. Groove Music opened (with no blue loading screen) before the start menu had time to animate out . I know that the 5400RPM Samsung Spinpoint(Seagate) drive in my desktop isn't that fast (Maxes out at 65MB/s, Compared to the 7200RPM drives in my server maxing out at 110MB/s), so I'm kinda confused at why these apps are launching so fast. My college friend's system with a 3GHz Xeon(don't know model number), a 120GB Toshiba SSD and 32GB RAM, seems only marginally more responsive compared to my system. I disabled fast boot on his system since it most certainly doesn't make sense to use on an SSD.

 

I have fast boot turned off and only have 4GB RAM (+ a 160GB drive used for pagefile until I can afford more ram), boot hdd is 2% fragmented. I also partitioned off the first 115GB of my boot hdd so I can easily upgrade to a 120GB SSD in the future.

 

Does Windows 10 have some kind of predictive memory caching? (Linux has memory caching but it's not predictive, the kernel only caches a file in memory after it's been explicitly opened)

Superfetch has been a thing since XP.

They did add another service though, Delivery Optimization.

since windows 8, applications formerly known as Metro, never actually shut off for real and always reside in memory

Googling and I came across this.

How WinX handles memory.

 

Windows 10 is using the combination of parallelizability and sequential reads to produce pages into memory once called. The new decompression should result in a speedier experience as Windows 10 is simultaneously decompressing data and reading it in parallel using multiple CPUs. Older versions of Windows may have felt sluggish because of the transfer rates between the disk.

Thanks everyone . I remember hearing about superfetch somewhere but didn't know what it was
