Small question about performance of IRS

first of all, thanks for this.

I have a small question. Is this faster than a normal hibernation for you?
I'm asking because a manual hibernation is way faster for me. My laptop takes a while to write the image into the IRS partition, something like 20 seconds, and the same amount of time to write it back in RAM on resume. I also noticed that it doesn't depend on how much RAM I'm using, unlike the normal hibernation, which in the same conditions allows me to resume the laptop in 10 seconds (including bootloader etc).

Is there a difference for you between this Intel Rapid Start hibernation and a regular hibernation? To me it looks like that the firmware simply copies the whole RAM, no matter what.

Thanks again.
