How to correctly re-measure the directory traversal time?

Question

go

I am doing a recursive traversal of directories, but there was such a problem that the program spends 14s of time on the first traversal, and 1s on subsequent traversals. Can I somehow make it so that the time is +/- stable?
I do a bypass through os.Walk

Answer 1

Rather, every time the measurement shows the correct results despite such a difference.
I think it's in the cache of data from the disk, due to caching, repeated bypasses work faster.
To be more precise, you need to see your code.
