Performance testing is used to verify that an app or web page will display quickly to the user and will continue to function as the number of users increases to peak loads. Performance is an important consideration for mobile applications because the connection speed of users is often slower and more variable for mobile users than desktop users. Surveys have shown that users will often stop using applications or web sites that load slowly.
Performance testing will typically consider the following items:
- Performance when device has low battery
- Performance and download speeds on a variety of network speeds (e.g. 3G, 4G LTE)
- Performance and potential lagging on a variety of mobile devices and OS versions
- Performance when disconnected from network
- Performance under heavy load by a large number of users
- Battery consumption
- Response time
- Resource utilization (memory and processor)
- Binary size of native applications
- Executive Order on Improving Customer Service in Government
- OMB Fast Track Process for Collecting Service Delivery Feedback
- OMB Guidance on Plain Language Writing Act
- OMB Memo on Information Collection under the Paperwork Reduction Act
