I don't see a call in any of the places responsible for reading directories and files in the kernel. Is this not sufficient? This is what I was referring to in my posts, which you argued with.

You're welcome to show me how I'm wrong. So far I made a point *and* defended it with evidence, whereas you've failed to show *any* evidence to the contrary other than to claim you optimized it. If you optimized it, you should very easily be able to quote some functions that you optimized.

I call bullshit.

"Should be close" - of course they'd be close. Reads are much quicker than writes, and hard disks have internal caching and read-ahead functionality. The hard drive is making up for the fact that FreeDOS is stupid. This doesn't mean FreeDOS has decent code.

Go ahead, quote some code. I did.
