What Are the Factors That Affect Upload and Download Speeds of OBS?

The OBS upload and download speeds may be affected by:

Default upper limit of the OBS read/write bandwidth allowed for a single Huawei Cloud account: 16 Gbit/s (which means the total GET and PUT bandwidths over both public and private networks)

If the actual bandwidth reaches this upper limit, flow control will be triggered.
Bandwidth of the purchased VM NIC

If the NIC bandwidth is lower than 16 Gbit/s, the node bandwidth will be limited by the VM bandwidth. You need to purchase multiple VMs to run concurrently to reach 16 Gbit/s.
Disk I/O and resource contention
