This topic describes the performance metrics and limits of OSS.
The following table describes the performance metrics and limits of OSS.
Item | Limit |
---|---|
Bandwidth | Default bandwidth limit: 10 Gbit/s in mainland China regions and 5 Gbit/s in regions
outside mainland China. When this limit is reached, requests are throttled.
Note When requests are throttled, the response header contains
x-oss-qos-delay-time: number , in which number indicates the time period during which requests are throttled. Unit: ms. For an upload
request, the exact time period during which requests are throttled is returned. For
a download request, the estimated time period during which requests are throttled
is returned. The time is estimated based on the throttling status and the object size.
If you require a greater bandwidth (10 Gbit/s to 100 Gbit/s), for example, if you have offline big data processing requirements, contact the technical support. |
Queries per second (QPS) | The limit of the total QPS for a single account is 10,000. The actual values that
can be achieved are different in the different read and write modes:
If you require a greater QPS, contact the technical support. |
