+> File shares performance is subject to machine network limits, available network bandwidth, IO sizes, parallelism, among many other factors. For example, based on internal testing with 8 KiB read/write IO sizes, a single Windows virtual machine, *Standard F16s_v2*, connected to premium file share over SMB could achieve 20K read IOPS and 15K write IOPS. With 512 MiB read/write IO sizes, the same VM could achieve 1.1 GiB/s egress and 370 MiB/s ingress throughput. To achieve maximum performance scale, spread the load across multiple VMs. Please refer [troubleshooting guide](storage-troubleshooting-files-performance.md) for some common performance issues and workarounds.
