The analysis of the Gradle build performance between two variants, varianta_gradle_8_13 and variantb_gradle_8_14_rc2, reveals minor differences in build times and task execution. The mean build time for varianta is 215.687 seconds, slightly higher than variantb at 215.076 seconds, showing a marginal improvement of 0.28%. Key tasks such as KotlinCompile, LinkApplicationAndroidResourcesTask, and KspTaskJvm show minor fluctuations in execution times between the two variants, with differences generally under 10%. Memory and CPU usage for all processes and specifically for the build process are nearly identical across variants, with maximum CPU usage hitting 100% for all processes in both variants. The total garbage collection counts in Gradle and Kotlin processes are also similar, indicating consistent memory management behavior between the two variants.

The performance comparison between varianta_main and variantb_z/metro reveals that variantb_z/metro generally has a shorter build time with a mean reduction of 25.1% (6.622 seconds). Notably, variantb_z/metro also exhibits higher CPU usage in build child processes, suggesting more intensive parallel task execution. In the Kotlin Build Reports, variantb_z/metro shows a significant increase in Compiler IR translation time, which could indicate more complex translation processes. Memory usage is slightly lower in variantb_z/metro across all processes, contributing to its efficiency.

The analysis of the Gradle build performance comparison data between two variants reveals notable differences in build times and task execution times. Variant B (variantb_z/metro) shows a faster overall build time with a mean reduction of 20.42 seconds (13.4% faster) compared to Variant A (varianta_main). Key tasks such as com.android.build.gradle.internal.tasks.MapSourceSetPathsTask and com.google.devtools.ksp.gradle.KspAATask also exhibit significant time reductions in Variant B. Memory usage is slightly lower in Variant B across all processes, with a maximum memory usage of 6.9 GB compared to 7.04 GB in Variant A. CPU usage is nearly identical for both variants, maxing out at 100% for all processes.

The analysis of the Gradle build performance comparison between varianta_main and variantb_lint_2g reveals several key findings. The overall build time for variantb_lint_2g is longer by approximately 73 seconds (7.3% increase) compared to varianta_main. In task execution, the most significant difference is observed in the :layer_0:module_0_1:lintAnalyzeDebug task, where variantb_lint_2g takes about 13.64 seconds longer than varianta_main. Memory and CPU usage across all processes are relatively similar between the two variants, with slight variations in peak values. The total garbage collection (GC) count was lower in variantb_lint_2g by 73 collections, indicating potentially more efficient memory management.

The analysis of the Gradle build performance data reveals minor differences between the two variants, with variant B showing a slight increase in overall build time by approximately 0.3 seconds (0.3%). Notably, the most time-consuming tasks across both variants include com.android.build.gradle.internal.lint.AndroidLintAnalysisTask, :core:designsystem:compileProdReleaseKotlin, and :core:common:lintAnalyzeJvmMain, with variant B generally performing slightly better in these tasks. Memory and CPU usage are nearly identical for both variants, with no significant differences observed. The total garbage collection counts for Gradle and Kotlin processes are slightly lower in variant B, suggesting marginally better memory management.

The performance comparison between two Gradle build variants, varianta_main_r8 and variantb_r8_different_process, reveals several key differences. The overall build time for variantb_r8_different_process is slightly higher by approximately 10.6 seconds (2.04% increase) compared to varianta_main_r8. Notably, variantb_r8_different_process shows a significant increase in memory usage, with a maximum of 14.24 GB compared to 11.2 GB for varianta_main_r8, marking a 27.14% increase. Additionally, variantb_r8_different_process has fewer total garbage collection (GC) events in the Gradle process but more in the Kotlin process, suggesting different memory management behaviors. The R8Task and L8DexDesugarLibTask are among the most time-consuming tasks, with variantb_r8_different_process showing longer execution times, especially in L8DexDesugarLibTask where the mean time increased by over 47%.

The Gradle build performance comparison shows a slight improvement in overall build times for variantb_kotlin_2_1_20 compared to varianta_main_2_1_0, with a mean time of 213.747 seconds versus 214.317 seconds, respectively. The most time-consuming tasks across both variants were ‘org.jetbrains.kotlin.gradle.tasks.KotlinCompile’, ‘com.android.build.gradle.internal.tasks.DexMergingTask’, and ‘com.android.build.gradle.tasks.PackageApplication’. Notably, the ‘com.google.devtools.ksp.gradle.KspTaskJvm’ task showed a significant timing variation of more than 10% between the two variants. In terms of resource consumption, both variants showed similar CPU and memory usage, with a slight increase in memory usage for variantb_kotlin_2_1_20.

The analysis of the Gradle build performance comparison data reveals that the variant variantb_no_xms generally takes longer to build than varianta_using_xms. The mean build time for variantb_no_xms is approximately 3.5% longer than varianta_using_xms. The most time-consuming tasks across both variants are :app:l8DexDesugarLibDemoDebug, :app:mergeExtDexDemoDebug, and :core:designsystem:compileDemoDebugKotlin. In terms of CPU and memory usage, both variants reach 100% CPU usage, but varianta_using_xms uses more memory. Garbage collection data shows more collections for variantb_no_xms.

The Gradle build performance comparison shows that the build times between the two variants are almost identical with a mean difference of just 99ms (0.05%). The variant with the Kotlin compiler and 3 workers (variantb_kotlin_compiler_3_workers) has slightly higher P90 values in most tasks, indicating that it might be slower in worst-case scenarios. The most time-consuming tasks across both variants are :app:l8DexDesugarLibDemoDebug, :app:mergeExtDexDemoDebug, and :core:designsystem:compileDemoDebugKotlin. Notably, the :app:mergeExtDexDemoDebug task is faster in variantb_kotlin_compiler_3_workers by 10.3%. CPU and memory usage are almost identical between the two variants.

The Gradle build performance comparison data reveals that variant B (variantb_main_parallel) generally performs better than variant A (varianta_main_g1). The mean build time for variant B is approximately 14.3 seconds, which is 6.6% faster than variant A’s mean build time of around 21.5 seconds. The most time-consuming tasks across both variants are :app:l8DexDesugarLibDemoDebug, :app:mergeExtDexDemoDebug, and :core:designsystem:compileDemoDebugKotlin. Significant differences in task execution times are observed in :app:transformDemoDebugClassesWithAsm and :core:designsystem:bundleLibCompileToJarDemoDebug. The CPU and memory usage are also slightly lower for variant B.
