What happens with a Windows Pagefile/swapfile on a cached disk?
Posted: Tue Jan 17, 2017 11:03 pm
I'm experimenting with Romex PrimoCache and learning more about different things along the way.
Leaving Primo out of the equation, I'd created my boot-system disk on SATA SSD 500GB. I tweaked the SSD as usually prescribed, and particularly to set the pagefile/swapfile to 2GB for VSS and other services that may need it.
But then, I let Windows create and manage a swapfile stored on my cached HDD. I have 16GB of RAM, but Windows puts a swapfile of 20GB on that HDD.
How much of this swapfile would be cached on the SSD eventually? Am I doing this properly?-- because it seems to work fine. I could also use part of my NVMe (caching-) SSD for a volume adequate or ample for a swapfile.
Any opinions? I don't think minimizing a swapfile helps, other than keeping it off a boot-SSD. Even my caching-NVMe-SSD or a regular SATA SSD caching-disk on two respective systems fail to show hard usage in TBW for those disks, using the respective bundled utilities for them.
And it seems the only thing you lose with a swapfile is time in boot, shutdown or restart. I don't care much about acceptable time-delays of that nature. Waking from Hibernation takes about as long as you would expect. The Hiberfil.sys I limited to the minimum 50%, since I can't put it on a storage disk that isn't also the boot-system disk.
