NornicDB vs Neo4j Performance Benchmark¶

TL;DR: NornicDB with Apple Metal GPU delivers 1.6-4.9x faster operations than Neo4j, with 35-47% additional boost from GPU acceleration.

🏆 Key Results (Northwind Dataset - Consolidated)¶

💻 Test Environment¶

macOS (Apple Silicon - Primary)¶

Windows (AMD - Secondary)¶

📊 Northwind Benchmark (48 nodes, 56 relationships)¶

Averaged across 3 runs (2 with Metal, 1 without). Variance: ±2-4%

🏆 Where NornicDB Dominates (2x+ faster)¶

✅ Where NornicDB Wins (1.0-1.5x faster)¶

⚠️ Where Neo4j is Competitive¶

📈 Metal GPU Acceleration Impact¶

Comparing NornicDB without Metal vs with Metal enabled:

Average Metal GPU boost: ~38% across all queries.

🔧 Optimizations Applied¶

Performance improvements implemented (no functionality changes):

📊 Performance Characteristics¶

Where NornicDB Excels¶

• Write operations: 3.3x faster (optimized WAL + in-memory indexing)
• Index lookups: 2x faster (simpler index structure)
• Simple traversals: 2x faster (less query planning overhead)
• Aggregations without GROUP BY: 2.8x faster
• Consistency: Lower variance (±0.8-1.8% vs ±1.4-3.8%)
• GPU acceleration: 35-47% boost with Apple Metal

Note: NornicDB has full WAL (Write-Ahead Logging) enabled by default for durability. The performance advantage comes from optimized WAL implementation + BadgerDB's efficient MVCC.

Where Neo4j is Competitive¶

• Full table scans: Get all products/customers (~equal)
• SUM with GROUP BY: Mature aggregation optimizer
• Memory optimization: Better for very large graphs (>1M nodes)

what does this data mean?

GitHub Copilot: Looking at these benchmark results comparing NornicDB (your custom graph database) vs Neo4j on the Northwind dataset, here's what the data tells us:

📊 Summary: NornicDB is Faster Overall¶

Key Metrics Explained¶

🏆 NornicDB vs Neo4j Comparison¶

Where NornicDB Dominates (2x+ faster):¶

Where They're Comparable:¶

Where Neo4j Wins Slightly:¶

• Aggregations with grouping (Products per category, Orders per customer) - Neo4j's mature query planner optimizes these better
• OPTIONAL MATCH patterns - Neo4j handles outer joins more efficiently

🎯 What This Means¶

1. NornicDB is production-ready for most workloads - consistently 1.5-4x faster than Neo4j on read operations

2. Write operations are MUCH faster - 3.5x faster create/delete (important for agent memory workloads)

3. Simple queries shine - Count, lookup by ID/name are blazing fast

4. Complex aggregations need work - Some GROUP BY queries are slower (this is where Neo4j's mature optimizer helps)

5. Consistency is good - Low rme values (2-4%) mean predictable performance

💡 Recommendations¶

Your parallel execution work should help with the aggregation queries (Products per category, Orders per customer) where NornicDB is currently slower. Those involve scanning + grouping large result sets - perfect for parallel execution!

Want me to profile any specific slow queries to identify optimization opportunities?

GitHub Copilot: ## 📊 NornicDB vs Neo4j Performance Breakdown (Metal GPU Enabled)

🔥 Overall: NornicDB is 1.5x - 4.3x faster across the board¶

Performance Comparison Table¶

🎯 Key Insights¶

Where NornicDB Dominates (2x+ faster):¶

Where They're Equal (~1x):¶

Where Neo4j Wins (0.6-0.98x):¶

📈 Metal GPU Impact¶

Comparing to your previous run without Metal:

Metal provides ~35-47% performance boost on most queries!

🔧 Optimization Opportunities¶

The two queries where Neo4j wins significantly:

1. Get all products (0.63x) - Returning all 16 products with all properties
2. Total quantity ordered per product (0.63x) - SUM aggregation with GROUP BY

These would benefit from:

• Parallel property serialization when returning many nodes
• Parallel SUM with partitioned aggregation for large groupings

Want me to optimize these specific queries?

Timothy-Sweet_cvsh: Get all customers 1,897 1,934 0.98x ⚠️ Neo4j wins slightly Products per supplier 1,898 1,931 0.98x ⚠️ Neo4j wins slightly Get all categories 1,884 1,949 0.97x ⚠️ Neo4j wins slightly Customers with order lists 1,865 1,948 0.96x ⚠️ Neo4j wins slightly Total qty ordered per product 1,169 1,843 0.63x ⚠️ Neo4j wins Get all products 1,141 1,801 0.63x ⚠️ Neo4j wins

check if they are easy performance gains such as regex not compiled up front if we can, better cleanup and management of things, etc.. CHANGE NO FUNCTIONALITY

GitHub Copilot: Let me investigate these slower queries to find easy performance wins without changing functionality.

Searched for regex regexp\.Compile|regexp\.MustCompile (**/nornicdb/**/*.go), 20 results

Good - the regex patterns are pre-compiled at package level. Let me check if there are any regex being compiled inside functions (hot paths):

Searched for regex regexp\.Compile\(|regexp\.MustCompile\( (**/nornicdb/**/*.go), 50 results

Found several regex patterns being compiled inside functions in create.go! Let me check those:

Read , lines 855 to 915

Read , lines 1000 to 1100

Read , lines 1100 to 1200

I found several regex patterns being compiled inside functions in hot paths. Let me also check if there are any in the executor or match files:

Searched for regex func.*\{[^}]*regexp\.(Must)?Compile (**/nornicdb/pkg/cypher/*.go), no results

Searched for regex regexp\. (**/nornicdb/pkg/cypher/executor.go), 1 result

Read , lines 2360 to 2380

Found one! regexp.MatchString compiles the regex every call. Let me also look for other common inefficiencies - strings.Split in loops, unnecessary allocations, etc:

Searched for regex regexp\.|strings\.Split|strings\.ToLower|strings\.ToUpper (**/nornicdb/pkg/cypher/match.go), 18 results

Let me also check how nodes are returned/serialized - this could be a bottleneck for "Get all products":

Searched for regex make\(map\[string\]|make\(\[\] (**/nornicdb/pkg/cypher/*.go), 20 results

Let me check the regex_patterns.go to see the structure and look for the regex cache opportunity:
