Summary

The analysis of the Gradle build performance data reveals that the transition from varianta_baseline to variantb_gradle-9.5.1 has led to a slight reduction in overall build time by approximately 9.5 seconds (3.57%). However, the configuration time has increased slightly by about 1.046 seconds (2.69%). Notably, the task :app:app:parseDebugLocalResources showed a significant reduction in execution time, decreasing by about 0.642 seconds (31.41%). Memory usage for all processes decreased from 8.61 GB to 8.31 GB, a reduction of about 3.48%. CPU usage remained maximally utilized at 100% for all processes in both variants.
