bpfilter performance across commits
Benchmark metrics
32 benchmarks
Each row shows performance data for a single benchmark. Runtime is the CPU time
measured for the most recent commit, and Instructions is the BPF instruction count
of the generated program. The Δ (delta) columns show the percentage change compared
to the mean of the previous N commits (e.g., "5 commits" compares against the average of
commits 2-6). Only statistically significant changes (z-score > 2.5) are colored:
green for improvements (faster or fewer instructions),
red for regressions. Uncolored values indicate changes within
normal variance. Click a benchmark name to jump to its historical chart below.
