Major Features: - Debug counter infrastructure for Refill Stage tracking - Free Pipeline counters (ss_local, ss_remote, tls_sll) - Diagnostic counters for early return analysis - Unified larson.sh benchmark runner with profiles - Phase 6-3 regression analysis documentation Bug Fixes: - Fix SuperSlab disabled by default (HAKMEM_TINY_USE_SUPERSLAB) - Fix profile variable naming consistency - Add .gitignore patterns for large files Performance: - Phase 6-3: 4.79 M ops/s (has OOM risk) - With SuperSlab: 3.13 M ops/s (+19% improvement) This is a clean repository without large log files. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# Mid Range MT Benchmark - Optimal Configuration
|
|
#
|
|
# Parameters discovered through performance tuning:
|
|
# - threads=4: Optimal for quad-core systems
|
|
# - cycles=60000: Sufficient iterations for stable results
|
|
# - ws=256: Working set that fits in L3 cache (4MB)
|
|
# - taskset -c 0-3: Pin to cores 0-3 for consistency
|
|
#
|
|
# Performance target: 95-99 M ops/sec
|
|
# vs System allocator: ~1.87x faster
