Summary
The analysis of the Gradle build performance data reveals several key insights across different metrics and task types. 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.
