How Fast Is It ?

[BrandyWine]

Just a ez test from OS read angle

time find / -type f > /dev/null

If you want how many regular files
find / -type f | wc -l

Here's my N150 using some basic NVMe and RAM
find / -type f | wc -l
98563

time find / -type f > /dev/null
0.000u 0.247s 0:00.24 100.0%

1/4sec to find 98563 files

It's just one way. Is your setup faster? Run it a couple of times.
