Doesn't it (Windows VFS layer) also lack the equivalent of dentry cache, making all metadata lookups slow?

The MFT describes resident (in-MFT) metadata about files, or non-resident (external to the MFT, but the MFT has a pointer) if the metadata does not fit within the MFT. The MFT itself is a database; Windows makes use of file system caching, be it in-memory or another caching mechanism, like on-device disk cache.
So why is it still pretty slow for file operations on DevDrive (no filters, async antivirus)? I found the performance improvement not that significant.
Doesn't match what I found.
