Summary

The analysis of the Gradle build performance data reveals a slight increase in overall build time when comparing the baseline variant (varianta_baseline) to the variantb_gradle-9.6.0. Specifically, the mean build time increased by approximately 3.6 seconds (1.3% increase), with the P90 time showing a more significant increase of 11.5 seconds (4.0% increase). Notably, the configuration times slightly decreased in the new variant by about 0.5 seconds. In terms of resource usage, there was a noticeable increase in memory consumption across all processes, with the maximum memory usage rising from 8.35 GB to 9.11 GB (9.1% increase). CPU usage remained maximized at 100% for all processes in both variants.

Detailed Report

1. Build Time Comparison

  • Overall Build Time:

    • Mean: Increased from 271.269 seconds to 274.904 seconds (+3.6 seconds, +1.3%).
    • P50: Increased from 270.452 seconds to 275.492 seconds (+5.04 seconds, +1.9%).
    • P90: Increased from 288.783 seconds to 300.299 seconds (+11.5 seconds, +4.0%).

  • Configuration Time:

    • Mean: Decreased from 39.154 seconds to 38.616 seconds (-0.538 seconds, -1.4%).
    • P50: Decreased from 39.954 seconds to 39.316 seconds (-0.638 seconds, -1.6%).
    • P90: Increased from 43.014 seconds to 43.956 seconds (+0.942 seconds, +2.2%).

2. Task Type Differences

  • Top Time-Consuming Tasks:
    • "org.jetbrains.kotlin.gradle.tasks.KotlinCompile": Slight increase in mean time from 3.325 seconds to 3.538 seconds.
    • "com.google.devtools.ksp.gradle.KspAATask": Virtually unchanged, mean time from 2.550 seconds to 2.551 seconds.
    • "com.android.build.gradle.internal.res.LinkApplicationAndroidResourcesTask": Increased from 1.967 seconds to 2.120 seconds.

3. Statistical Patterns

  • Tasks such as "com.android.build.gradle.internal.tasks.DexMergingTask" showed a decrease in execution time, while "com.android.build.gradle.internal.res.LinkApplicationAndroidResourcesTask" increased notably in the P90 metric from 2.290 seconds to 2.818 seconds.

5. CPU & Memory Usage Analysis

  • CPU Usage:

    • All processes: Maximized at 100% for both variants.
    • Build process: Slight increase from 95.63% to 95.73%.
    • Build child processes: Slight decrease from 92.67% to 92.17%.

  • Memory Usage:

    • All processes: Increased from 8.35 GB to 9.11 GB (+9.1%).
    • Build process: Increased from 4.06 GB to 4.36 GB (+7.4%).
    • Build child processes: Increased from 3.22 GB to 3.70 GB (+14.9%).

The data indicates that while the newer Gradle variant (variantb_gradle-9.6.0) slightly increases build times, it also uses more memory, which could be a concern for resource-constrained environments. The configuration time improvements are minimal, suggesting that the newer version’s changes might not significantly optimize configuration phases.
