 When increasing the virtual hub capacity, the virtual hub router will continue to support traffic at its current capacity until the scale out is complete. It may take up to 25 minutes for the virtual hub router to scale out to additional routing infrastructure units. It's also important to note the following: currently, regardless of the number of routing infrastructure units deployed, traffic may experience performance degradation if more than 1.5 Gbps is sent in a single TCP flow.

+> Regardless of the virtual hub's capacity, the hub can only accept a maximum of 10,000 routes from its connected resources (virtual networks, branches, other virtual hubs, etc).

 ### Configure virtual hub capacity
 
 Capacity is configured on the **Basics** tab **Virtual hub capacity** setting when you create your virtual hub.

+* **Sum Aggregation Type** - The **sum** aggregation type shows you the total number of bytes that traversed the virtual hub router during a selected time period. For example, if you set the Time granularity to 5 minutes, each data point will correspond to the number of bytes sent in that 5 minute interval. To convert this to Gbps, you can divide this number by 37500000000. Based on the virtual hub's [capacity](hub-settings.md#capacity), the hub router can support between 3 Gbps and 50 Gbps. The **Max** and **Min** aggregation types aren't meaningful at this time.
