Unfortunately I can’t say too much publicly on HN. But one of the big shortcomings is dealing with hundreds of files. It doesn’t even matter if those are big or small files (I’ve had experience with both).

Services like DataSync show that the underlying infra can be performant. But it feels almost impossible to replicate that on EFS via standard POSIX APIs. And unfortunately one of our use cases depend upon that.

If feels, to me at least, like EFS isn’t where AWSs priorities lie. At least if you compare EFS to FSx Lustre and recent developments to S3. Both of which has been the direction our AWS SAs have pushed us.
