Summary

The analysis of Gradle build performance between two variants, varianta_agp_8.12 and variantb_agp_9-alpha01, reveals a slight increase in overall build time in the newer variant by approximately 0.35 seconds (0.35% increase). The configuration time also shows a minor increase by about 0.09 seconds (2.15% increase). The most time-consuming tasks across both variants include :core:cart:compileDebugKotlin, :core:identity:compileDebugKotlin, and :core:contact:compileDebugKotlin, with marginal differences in execution times between the variants. Memory usage is slightly higher in variantb_agp_9-alpha01 for all processes and specifically for build child processes. CPU usage remains nearly identical across both variants. The total garbage collection counts are slightly reduced in the newer variant.
