Tiny Step 2: drain interval optimization (default 1024→2048)
Completed A/B testing for TLS SLL drain interval and implemented
optimal default value based on empirical results.
Changes:
- core/box/tls_sll_drain_box.h: Default drain interval 1024 → 2048
- TINY_DRAIN_INTERVAL_AB_REPORT.md: Complete A/B analysis report
Results (100K iterations):
- 256B: 7.68M ops/s (+4.9% vs baseline 7.32M)
- 128B: 8.76M ops/s (+13.6% vs baseline 7.71M)
- Syscalls: Unchanged (2410) - drain affects frontend only
Key Findings:
- Size-dependent optimal intervals discovered (128B→512, 256B→2048)
- Prioritized 256B critical path (classify_ptr 3.65% in perf profile)
- No regression observed; both classes improved
Methodology:
- ENV-only testing (no code changes during A/B)
- Tested intervals: 512, 1024 (baseline), 2048
- Workload: bench_random_mixed_hakmem
- Metrics: Throughput, syscall count (strace -c)
