Summary

The analysis of the Gradle build performance data reveals minor differences between the two variants, varianta_9.2.1 and variantb_9.3.0. The overall build time for varianta_9.2.1 averaged 638.4 seconds, slightly faster than variantb_9.3.0 at 639.8 seconds, a difference of about 1.4 seconds. Configuration times also showed a slight increase in variantb_9.3.0 by approximately 0.9 seconds. The most time-consuming tasks across both variants include :core:account:kspDebugKotlin, :core:analytics:kspDebugKotlin, and :core:article:kspDebugKotlin, with execution times closely matched between variants. Memory and CPU usage for all processes and specifically for the build processes were nearly identical in both variants, indicating consistent resource utilization. The total garbage collection counts were also similar, with varianta_9.2.1 having 290 collections compared to 288 in variantb_9.3.0.
