@Marcuzzz Thanks for your feedback

Hmm, it's probably due to small file size, when some data gets left in operating system FS cache. You may try specifying larger file size
I'll take a look for possible solutions in February as now I'm overloaded with the main work

I have similar results. Looking at the Windows Task Manager, seems like nothing is actually read from the disk.
