Summary
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.
