Product Performance
During the public beta period, only the 500 MB/s/TiB baseline version is supported. The cluster scale deployed during the public beta period is limited, and throughput and IOPS will increase linearly with capacity. If you want to try the maximum throughput of TB/s and tens of millions of IOPS, please contact technical support in a timely manner.
Quick Reference Table
No QoS policies are implemented during the public beta period. The following performance indicators show the optimal values actually tested for the UPFS file system on the public cloud.

Relationship between UPFS Performance and Instance Performance
The IO performance of a virtual machine instance has a linear relationship with its CPU configuration. More CPU cores result in higher storage IOPS and throughput. Write throughput is limited by the instance’s CPU configuration.
If UPFS performance does not exceed the IO storage capacity of the instance, the actual storage performance is subject to UPFS performance.
If UPFS performance exceeds the IO storage capacity of the instance, the actual storage performance is subject to the instance’s storage performance.
If the number of instance cores is not listed in the table below, the instance performance is the maximum performance not exceeding that core count. For example, a CPU with 50 cores has the same storage IO performance as a 48-core CPU.
