⚠️ 126 benchmarks spent significant time in system calls

System calls cannot be consistently instrumented, so they are not included in the measure, which understates the real cost. Please switch to the Walltime instrument to accurately measure system calls.

Measurement and system calls

• du_all_wide_tree[(5000, 500)]
• sort_mixed_utf8_locale
• sort_reverse_utf8_locale
• sort_unique_utf8_locale
• cksum_multiple_files
• sort_very_long_lines_utf8_locale
• factor_multiple_u64s[2]
• factor_64bit_semiprime
• cksum_default
• du_summarize_balanced_tree[(5, 4, 10)]
• …and 116 more

ℹ️ 1 benchmark has no flame graph

The flamegraph could not be generated because too much time was spent in runtime internals, making the visualization not useful for performance analysis.

• sort_dictionary_order[500000]

⚠️ Different runtime environments detected

Footnotes

1. 70 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on main (f4f39e0) during the generation of this report, so 1747ba1 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
