I can confirm that creating snapshots in HF25 is very fast.
For a plain witness node it took about 3-5 seconds to make a HF25 snapshot.
It was so fast I couldn't believe it.
Also my replay after installing HF25 took less than 9 hours!
This is on a pretty fast machine with lots of RAM.

Well done!
Thanks for the performance info, I had no idea a plain witness node could create a snapshot so fast.
It takes 10-11 seconds here.
