I'd like to optimize very specific scenarios where almost every directory is enumerated on an NTFS volume (on an HDD). When an application spends a considerable time reading a file with inefficient access patterns, a cheap trick can be utilized to speed it up: reading the whole file sequentially in big chunks beforehand into memory, so it gets cached by the system. Then the application's reads will be fulfilled from memory by the cache manager, so it's going to be really fast.
I thought I would employ the same "trick" for this problem, as well. However, it doesn't seem like that the MFT can be accessed easily. Every code I could find on the internet opens a handle to the volume itself and performs raw reads on it. This works great in the sense that you can actually read the MFT or anything else on the drive, but it seems like that no caching is performed by the cache manager for these reads. I speculate this is because it's not opened as a regular file.
Is there a way to either open the MFT as a regular file or somehow perform reads on it in big chunks in a way that will populate the file cache with its content?
