Yes. Async I/O in Windows happens at the file system level, so the answer is yes, by default. Command queues are supported by default as well, as this is a Storport virtual miniport driver (which supports command queues).

Agree. The Projected File System is very limited compared to WinFsp, Dokany or CBFS. I have looked at it quite extensively as my own WinFsp open source software is in the same space.

Dokan and CBFS are more like WinFsp (another project of mine) in that they allow you to create file systems rather than "disks". I like to think that WinFsp is very stable software. I am working to bring WinSpd to the same levels

Good question. Unfortunately I do not know enough about iSCSI to answer this question fully. In my case I wanted a simple way to create "SCSI disks" using a user mode process. Since I had already created WinFsp, which has a solid

WinFsp allows you to create file systems. This project allows you to create disks that can be formatted with existing disk file systems (e.g. NTFS). They both have their uses but in general I think WinFsp is more useful for most. I am not f

Of course. I can see a couple of ways that this can happen: - P/Invoke. - Recompiling the library in C++/CLI mode.

Thanks. The implementation is very stable because WinFsp is tested regularly and rigorously. Please read about the WinFsp Testing Strategy here: https://github.com/billziss-gh/winfsp/wiki/WinFsp-Testing

BTW, here is how FSX calls CreateFileMappingW. https://github.com/billziss-gh/secfs.test/blob/60f9f44b87731... I do not see a big difference to the fsbench call. It may be that fsbench attempts to make a mapp

MEMFS limits how many files you can create (up to 1024 by default). Try running it with the parameter -n set to 100000, which will allow you to create up to 100000 files. Examples command lines: WinFsp: memfs -t 0 -n 100000 -m Z:

I will change the title to say "Faster than Dokany" without mentioning NTFS. The deception is not intentional. For me it was important to verify that my project is not slower than NTFS when using my test file system, which is an

Please suggest a more appropriate title and I will be happy to change it if it better conveys the results. Please also note that I want to convey that my solution is faster than Dokany, which is a competitor solution.
