The overall build times for varianta_9.0.0-rc1 averaged around 878.54 seconds, slightly slower than variantb_8.14.2 at 869.71 seconds, showing a minor difference of about 1%. Among the most time-consuming tasks, :layer_0:module_0_1:compileDebugKotlin and related Kotlin compilation tasks consistently took longer in varianta_9.0.0-rc1 compared to variantb_8.14.2. Memory usage was slightly higher in variantb_8.14.2 with a maximum of 12.75 GB compared to 12.67 GB in varianta_9.0.0-rc1. CPU usage for all processes hit the maximum of 100% for both variants, indicating full utilization during the build. The total garbage collection counts were slightly higher in varianta_9.0.0-rc1 for both Gradle and Kotlin processes, suggesting a bit more frequent memory cleanup.

The performance comparison between two Gradle build variants reveals minor differences in build times and resource usage. The mean build time for varianta_main is 515.286 seconds, while variantb_agp_8_10_1 is slightly longer at 516.571 seconds, marking a 0.25% increase. The most time-consuming tasks include com.android.build.gradle.internal.tasks.R8Task and com.android.build.gradle.internal.tasks.L8DexDesugarLibTask, with notable differences in execution times between the variants. CPU and memory usage across all processes and specifically for the build processes are nearly identical, with variantb_agp_8_10_1 showing a slight decrease in memory usage.

The analysis of the Gradle build performance data reveals a slight increase in overall build time when comparing variant B (AGP 8.10.1) to variant A. Specifically, the mean build time for variant B is approximately 0.61 seconds longer than variant A, representing a 0.6% increase. The P90 build times show a more pronounced difference, with variant B taking about 6.24 seconds longer than variant A, a 2.7% increase. In task execution, the most significant time differences are observed in tasks like :app:transformDemoDebugClassesWithAsm and :app:jacocoDemoDebug, where variant B shows increased execution times. Memory and CPU usage across all processes and specifically for the build processes are relatively stable with minor fluctuations. The total garbage collection (GC) counts are slightly higher in variant B for both Gradle and Kotlin processes, indicating a marginal increase in memory management activities.

The analysis of the Gradle build performance data reveals a notable improvement in overall build times when comparing variant B (metro_0_3_2) to variant A (anvil). Specifically, variant B is faster by approximately 6.7 seconds (26.012s for A vs. 19.291s for B), translating to a 25.8% decrease in build time. This improvement is consistent across the 50th and 90th percentiles as well. In task execution, the :app-scaffold:compileDebugKotlin task shows a significant increase in execution time in variant B, while :app-scaffold:kspDebugKotlin is notably faster. The Kotlin build reports highlight a substantial increase in IR translation time for variant B, suggesting a potential area for optimization. Memory and CPU usage are slightly higher in variant B for all processes, with the build child processes in variant B utilizing significantly more CPU resources. Lastly, garbage collection data indicates fewer total collections in variant B, suggesting more efficient memory management.

The performance analysis of the two Gradle build variants, varianta_anvil and variantb_metro_0_3_2, reveals significant differences in build times and task execution. variantb_metro_0_3_2 shows a faster overall build time by approximately 22.2 seconds (14.1%) compared to varianta_anvil. Notably, the com.google.devtools.ksp.gradle.KspAATask and org.jetbrains.kotlin.gradle.tasks.KotlinCompile tasks in variantb_metro_0_3_2 are considerably slower, indicating potential areas for optimization. Memory usage is slightly lower in variantb_metro_0_3_2 across all processes, with a maximum difference of about 0.19 GB. The Kotlin Build Reports highlight variantb_metro_0_3_2 as having a higher compiler IR translation time and more intensive code analysis, suggesting more complex operations despite the overall faster build time.

The performance comparison between varianta_main and variantb_lint_1.5g reveals significant differences in build times and resource utilization. variantb_lint_1.5g shows a notable reduction in overall build time, clocking in at approximately 1057.511 seconds compared to varianta_main’s 1642.304 seconds, marking a decrease of around 35.6%. This variant also uses less memory, with a maximum of 11.64 GB compared to varianta_main’s 13.69 GB. However, CPU usage is slightly higher in variantb_lint_1.5g for the build process, peaking at 93.95% versus 92.00% in varianta_main.

The performance comparison between two Gradle build variants shows a slight improvement in overall build time for variant B (218.791s) compared to variant A (221.317s), with a decrease of about 1.14%. The most time-consuming tasks across both variants include :app:l8DexDesugarLibDemoDebug, :app:mergeExtDexDemoDebug, and :core:designsystem:compileDemoDebugKotlin, with variant B generally showing better performance in these tasks. Memory usage is slightly lower in variant B for all processes and build child processes. The total garbage collection counts are slightly higher in variant B for both Gradle and Kotlin processes.

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.
