# Performance guidelines
To provide the best possible LINE MINI App experience to your users, take the performance of LINE MINI App into consideration.
A good reference regarding the importance of HTML5 performance, Why does speed matter? (opens new window), can be found on the Google Developers site.
LINE recommends the following score.
|Performance measurement tool||Score|
|Lighthouse (opens new window)||Performance: 50 and above|
- Measure without executing LINE Login. When LINE Login is executed simultaneously, the performance of the LINE Login page is measured, preventing LINE MINI App's performance from being measured.
- Be sure to measure in the production environment (real environment). Note that the network environment can affect the performance score.
