Will Dynamically sized VHDs affect startup speed? - zjqzero - 08-11-2024

As ventoy support fixed/dynamic size VHD for Windows,
If I have a 20GB dynamic size VHD, actually size is 10GB on disk.
After boot from this VHD, I see it's actual size will change to 20GB.
An additional 10GB of space has been allocated.
I want to know if this additional allocation takes up too much time?
If it's a 100GB VHD actually using 10GB, will it take more time to boot?
