Is mmap really that broken on Windows? Or is the poster just confused that the data stays in the page cache? But that’s what the page cache does - that memory will be used for other things if needed, but if the memory is not needed it might as well keep the old data in cache.

No, mmap on Windows is fine. A generous, charitable statement would be that the OP on that thread is very confused, but based on some comments elsewhere on this thread about jart attracting a chorus of haters, it seems more likely that they're just trolling.

There's a weird breed of programmer who only wants to see the free memory column in top be maximized. I bought all this RAM and I want to make sure none of it is used in case I want to use it later.
