# Performance guidelines
In order to provide the best possible LINE MINI App experience to your users, please take the performance of LINE MINI App into consideration.
A good reference regarding the importance of HTML5 performance, Why Performance Matters (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|
- Please 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). Please note that the network environment can affect the performance score.
