Microsoft itself admits there are performance issues with NTFS, which is one reason they created ReFS.
For example ReFS removed the MFT which caused various problems.

The MFT was annoying because if you create 1 mil files, and the delete them, the MFT will not be shrunk back.
Have you ever benchmarked it against NTFS? With the same exact set of FS filter drivers running on both? How much does the performance differ?
