Even with Defender etc off, it is not fun. Lots of small file IO brings it on its knees. Some wants to blame the Windows I/O system, I don't know, but what I do know is that when people choose NTFS it is because they haven't an alternative. Nobody chooses it based on its quality attributes. I dare to say there is no NTFS system that is faster than an EXT4 system.
If even MS internal teams rather want to avoid it, it seems like it isn't a great offering. https://news.ycombinator.com/item?id=41085376#41086062
NTFS on Linux should be near-par with ext4 on Linux.
Remember, I said the _file system_ was just fine. It's that extensible architecture above all file systems on NT that causes grief.
The only method to 'turn off' Defender is to use DevDrive, which enforces ReFS, and even then you only get async Defender, it's not possible to completely disable.
