What Are the Factors That Affect Upload and Download Speed of OBS?
The OBS upload and download speed may be affected by:
-
The default upper limit of the OBS read/write bandwidth allowed for a single 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 resources consumed by other processes
