Nathan posted a comment on discussion AtomicParsley forum

I noticed if I run Atomic Parsley from the command line on one file, then start a second, the second will process much faster (as indicated in command window progress bar. Both file same size. Is this normal for AP? I've read up on why MP4 tagging is slower than say MKV, but the inconsistent processing times made me think I could jumpstart it? Run then cancel an operation on a tiny MP4 file, then run desired MP4 at the quicker rate?
