The overall build time for <code>varianta_gradle_9_1_0</code> averaged 466.318 seconds, slightly higher than <code>variantb_jdk_25_parallel</code> at 448.495 seconds, marking a decrease of about 3.82%. Configuration times also show a decrease from 59.939 seconds in <code>varianta_gradle_9_1_0</code> to 53.989 seconds in <code>variantb_jdk_25_parallel</code>, a reduction of approximately 9.92%. Notably, garbage collection (GC) was more efficient in <code>variantb_jdk_25_parallel</code> with significantly fewer total collections (74) compared to <code>varianta_gradle_9_1_0</code> (157). Memory usage peaked slightly higher in <code>variantb_jdk_25_parallel</code> at 11.49 GB compared to 10.98 GB in <code>varianta_gradle_9_1_0</code>. CPU usage was maximized at 100% for both variants, indicating full utilization during the builds.https://cdsap.github.io/Telltale/posts/2025-09-20-cdsap-219-experiment/Sat, 20 Sep 2025 00:00:00 +0000https://cdsap.github.io/Telltale/posts/2025-09-20-cdsap-219-experiment/The analysis of the Gradle build performance data reveals some key differences between the two variants, <code>varianta_gradle_9_1_0</code> and <code>variantb_jdk_25</code>. The overall build time for <code>varianta_gradle_9_1_0</code> averaged 461.379 seconds, slightly faster than <code>variantb_jdk_25</code> at 469.345 seconds, a difference of about 7.966 seconds or approximately 1.7%. The configuration time showed <code>varianta_gradle_9_1_0</code> to be slower on average, taking 57.628 seconds compared to 55.901 seconds for <code>variantb_jdk_25</code>, a difference of 1.727 seconds or about 3.1%. Task execution times varied significantly between variants, with <code>variantb_jdk_25</code> generally taking longer in tasks related to Kotlin compilation and Android resource linking. Memory usage was slightly higher in <code>variantb_jdk_25</code> across all processes, with a maximum of 10.97 GB compared to 10.95 GB in <code>varianta_gradle_9_1_0</code>. CPU usage was nearly maxed out for both variants. The total garbage collection counts were higher in <code>varianta_gradle_9_1_0</code> with 157 collections compared to 120 in <code>variantb_jdk_25</code>.https://cdsap.github.io/Telltale/posts/2025-08-31-cdsap-211-experiment/Sun, 31 Aug 2025 00:00:00 +0000https://cdsap.github.io/Telltale/posts/2025-08-31-cdsap-211-experiment/The analysis of the Gradle build performance between <code>varianta_jdk_17</code> and <code>variantb_jdk_21</code> reveals several key insights. The overall build time for <code>varianta_jdk_17</code> averages 396.626 seconds, while <code>variantb_jdk_21</code> is slightly faster at 381.929 seconds, showing a reduction of approximately 14.697 seconds (3.7%). The configuration times are very close, with <code>varianta_jdk_17</code> averaging 44.278 seconds and <code>variantb_jdk_21</code> at 43.845 seconds. Notably, the most time-consuming tasks across both variants include <code>:core:cart:compileDebugKotlin</code>, <code>:core:identity:compileDebugKotlin</code>, and <code>:core:contact:compileDebugKotlin</code>, with <code>variantb_jdk_21</code> generally performing better in these areas. Memory usage is higher in <code>variantb_jdk_21</code> across all processes, with a maximum of 10.84 GB compared to 10.31 GB in <code>varianta_jdk_17</code>. CPU usage is nearly maxed out for both variants. The total garbage collection counts are slightly higher in <code>variantb_jdk_21</code> with 139 collections compared to 131 in <code>varianta_jdk_17</code>.
