File system performance


400 MB/s/TiB baseline for CPFS for Lingjun (public preview)


  • Read throughput: min{400 × Capacity (TiB), 400,000} MB/s

  • Write throughput: min{200 × Capacity (TiB), 200,000} MB/s

The throughput can be up to 2 TB/s. If you want to increase the throughput, submit a ticket.


  • Read IOPS: min{6,800 × Capacity (TiB), 6,800,000}

  • Write IOPS: min{2,300 × Capacity (TiB), 2,300,000}

The IOPS can be up to 30,000,000. If you want to increase the IOPS, submit a ticket.
