Nem is ertem, hogy hibernation eseten miert nem uriti a rendszer a cache-eket
Milyen cache-re gondolsz? S4-nél még RAM context sem marad meg.
hatalmas pazarlas kiirni a vinyora valamit ami eleve onnan szarmazik, hogy aztan beolvassuk es talan egyszer hasznaljuk is
A "talán" itt nem "talán", hanem "következő boot-nál garantáltan", ui. a kernel session-t menti:

Now here’s the key difference for Windows 8: as in Windows 7, we close the user sessions, but instead of closing the kernel session, we hibernate it. Compared to a full hibernate, which includes a lot of memory pages in use by apps, session 0 hibernation data is much smaller, which takes substantially less time to write to disk. If you’re not familiar with hibernation, we’re effectively saving the system state and memory contents to a file on disk (hiberfil.sys) and then reading that back in on resume and restoring contents back to memory. Using this technique with boot gives us a significant advantage for boot times, since reading the hiberfile in and reinitializing drivers is much faster on most systems (30-70% faster on most systems we’ve tested).
Egy (másik) példa, ahol ez kellemetlen lehet: virtuális gépek copy-on-write diszkjeinél. A kernel session mentése simán felzabálhat 250-300 MB helyet (4G RAM alatt nem gondolom, hogy bárki is indítana win8 VM-et):
and in the case of our fast startup usage, it’s typically ~10-15% of physical RAM but varies based on drivers, services, and other factors
