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 experience slow upload or download, perform the following operations:
- Check the network.
Ping the OBS endpoint in the current region, for example, ping obs.cn-north-1.myhuaweicloud.com, to check the network latency and packet loss rate.
- Check whether OBS is accessed over internal networks.
For details, see How Do I Determine Whether OBS Is Accessed from the Intranet?.
- 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.
- For batch upload, you can add -j and -p parameters, and raise the parameter values, and check whether the speed is improved. For more information, see Fine-Tuning obsutil Performance
