Dir scan

[Roedy Green]

I have not done benchmarks to prove this, but it seems to me when Java
scans the directory tree of a drive it takes MUCH longer than when a
native windows app does it. I wondered if anyone has investigated
this, and if they know what Java is doing that adds so much overhead.

"Here is a point of no return after which warming becomes unstoppable
and we are probably going to sail right through it.
It is the point at which anthropogenic (human-caused) warming triggers
huge releases of carbon dioxide from warming oceans, or similar releases
of both carbon dioxide and methane from melting permafrost, or both.
Most climate scientists think that point lies not far beyond 2°C (4°F) C hotter."

Check the source code.

Maybe Java does a JNI call per file. And that adds some overhead.
