> You're also mounting it from Linux, which is just... weird. Nobody (for some values of nobody) does this. The sole purpose for this service is to provide backwards-compatible file shares for Windows servers and desktops.

That's not what Azure's marketing material says:

Serverless file shares

"Store your files on a distributed file system built from the ground up to be highly available and durable."

"Take advantage of fully managed file shares mounted concurrently by cloud or on-premises deployments of Windows, Linux, and macOS."

"Use integration with Azure Kubernetes Service (AKS) for easy cloud file storage and management of your data using NFS or SMB file shares."

Azure explicitly markets this for Linux and Kubernetes. If it performs terribly on Linux, that's Azure's problem, not mine.

> Benchmarking cloud services can be tricky because they have odd quirks such as IOPS-per-GB ratios, so nearly empty storage can be much slower than you'd expect!

These managed services charge premium prices - they should deliver premium performance. At those prices, "quirks" and "you need to fill it up first" aren't acceptable excuses.

I don't believe anything Microsoft's marketing department says either.

I've had similar issues with Amazon's equivalent too, where I tried to use EFS for a tiny website and I got something like 0.1 IOPS!

I do like the design of ZeroFS, and it irks me that competing solutions make local caching and buffering weirdly difficult. For example, Azure Premium SSD v2 disks no longer support local SSD caches! It's also annoyingly hard to combine the local cache disks you do get with remote disks using Windows Server, it insists on trying to detect the "role" of each disk instead of just letting admins specify that.

Using something like ZeroFS could be a nice trick for getting decent price/performance on public cloud platforms. My only concern is integrity and durability: what testing have you done to validate that it doesn't lose data even in corner-cases?

There's always going to be uncertainty with software that young, but the CI is pretty expensive and we didn't yet receive corruption-related reports. https://github.com/Barre/ZeroFS/tree/main/.github/workflows
