[Data Barnacle] Run memory performance indicator repair
- Modules involved: Performance Quality - Performance Data - Running Performance - Running Memory Analysis
- Date of repair: March 19, 2025
- Description of the defect: iOS side of the average memory and memory growth statistics and the actual run-time memory index data inconsistent.
- Update: In order to solve the problem of the accuracy of memory indicators, we have adjusted the statistical caliber of memory indicators (only changes in statistical dimensions, Does not affect other aspects of Weixin Mini Program and more accurately reflects the actual memory usage of the current Mini Program. For specific adjustments and statistical rules, refer to the note below.
- **** In order to enable developers to master the performance data of Weixin Mini Program,The underlying framework of the Mini Program will sample existing network users with a certain probability, and users who need to report performance data will report data at a definite time interval (sampling interval is 1 minute). The specific statistical rules are as follows: -iOS side: Because Weixin Mini Program and WeChat guest are in the same process, so the average memory statistic value is the sum of WeChat guest and Mini Program memory.
- Android: Although the sampling interval for Android is 1 minute, Android 9.0 and above limits the frequency of runtime memory acquisition, requiring a interval of about 5 minutes to acquire new memory values.
