Slow Upload and Download Through obsutil

OBS does not limit the upload or download rate, nor does obsutil limit the data transfer rate.

If obsutil is used to upload and download files over the public network, the bandwidth is determined by the public network bandwidth. If internal networks are used, the network condition is determined by the network adapter, disk I/O, and restrictions on resource preemption.

If you are experiencing slow upload or download, do as follows:

1. Check the network.

   Ping the OBS endpoint (for example, obs.ap-southeast-1.myhuaweicloud.com) in the current region to check the network latency and packet loss rate.

   Regions and Endpoints

2. Check whether OBS is accessed over internal networks.

   For details, see Querying the OBS Network Segment and Determining the Access Type

3. For batch uploading or downloading small files in huge numbers, the speed is mainly determined by TPS (number of files processed in a second) instead of the bandwidth.
4. For batch upload, you can add -j and -p parameters, and raise the parameter values, and check whether the speed is improved. For details, see Fine-Tuning obsutil Performance.
