4. PERFORMANCE BENCHMARKS

4.1 Insert Throughput Test

Test Configuration:

• Records: 1,000 orders
• Duration: 355.15ms
• Configuration: synchronous_commit=on (production default)

Results:

Throughput: 2,815.71 inserts/sec
Baseline (Wave 131): 2,979 inserts/sec
Difference: -164 ops/sec (-5.5%)
Performance: 94.5% of baseline
Status: ✅ PASS

Analysis:

• Wave 131 baseline used synchronous_commit=off (faster but less durable)
• Current configuration uses synchronous_commit=on (production safe)
• 5.5% performance reduction is acceptable trade-off for ACID compliance
• Throughput still exceeds 2,800 ops/sec minimum threshold

4.2 Query Performance Tests

Test Type	Latency	Status	Details
Simple SELECT	0.463ms	✅ Excellent	Basic row retrieval
Complex JOIN	1.073ms	✅ Excellent	orders LEFT JOIN fills
Aggregation	2.350ms	✅ Excellent	GROUP BY with COUNT/SUM/AVG
Index Scan	0.532ms	✅ Excellent	symbol + status filter
Concurrent Writes	1,050 inserts/sec	✅ Good	100 orders in 95ms

All queries completed in <5ms - well within HFT requirements.

4.3 Batch Insert Performance

Temporary Table Test:

• Created temp table for performance testing
• Inserted 1,000 orders in 12.744ms
• Throughput: ~78,500 inserts/sec (batch mode)
• Query on 1,000 rows: 0.896ms (indexed)
• Aggregation: 3.890ms (4 groups)
• Time-range query: 1.099ms

Production Table Test:

• Real orders table with triggers and constraints
• 1,000 inserts in 355ms = 2,815 inserts/sec
• 100 inserts in 95ms = 1,050 inserts/sec (simulated concurrency)

10. CONFIGURATION RECOMMENDATIONS

Current Configuration (Production Safe)

synchronous_commit = on              # ACID compliance (current)
max_connections = 100                # Adequate for HFT
shared_buffers = 7954MB              # High performance
effective_cache_size = 23864MB       # Optimal
work_mem = 5091KB                    # Reasonable

Optional: High-Throughput Mode

For non-critical workloads where throughput > durability:

-- WARNING: Use only for non-critical data
ALTER SYSTEM SET synchronous_commit = off;
SELECT pg_reload_conf();

-- Expected improvement: 2,815 → ~2,979 ops/sec (+5.8%)
-- Risk: Potential data loss on system crash (last ~200ms of transactions)

Recommended: Keep Current Settings

• Current configuration prioritizes durability and ACID compliance
• 2,815 ops/sec is well above requirements for production HFT
• 99.97% cache hit ratio indicates excellent memory utilization
• No immediate tuning required

11. KNOWN ISSUES AND LIMITATIONS

Minor Observations

1. TimescaleDB Hypertables:

   • Status: Not configured
   • Impact: None (extension ready for future time-series optimization)
   • Action: Consider creating hypertables for market_events table if high-frequency data accumulates

2. Redis Cache Empty:

   • Status: 0 keys present
   • Impact: None (cache ready for use)
   • Action: Cache will populate automatically when services start using it

3. Some Indexes Unused:

   • idx_orders_venue_status: 0 uses
   • idx_orders_account_status: 1 use
   • Impact: None (indexes waiting for production traffic patterns)
   • Action: Monitor index usage and consider dropping if consistently unused

4. Schema Mismatch (Test Scripts):

   • Issue: Initial test scripts assumed price column (found limit_price instead)
   • Impact: None (test scripts corrected)
   • Resolution: Updated test scripts to use correct schema (bigint for prices)

No Blocking Issues

• ✅ All critical systems operational
• ✅ No data loss or corruption
• ✅ No performance bottlenecks
• ✅ No security vulnerabilities in database layer

APPENDIX B: Performance Tuning Guide

When to Consider Tuning

1. Insert throughput <2,500 ops/sec:

   • Consider synchronous_commit=off (if data loss acceptable)
   • Increase shared_buffers (if more RAM available)
   • Batch inserts (use COPY or multi-row INSERT)

2. Query latency >10ms:

   • Analyze slow queries with EXPLAIN ANALYZE
   • Add missing indexes
   • Increase work_mem for sorting/aggregation
   • Consider prepared statements

3. Cache hit ratio <95%:

   • Increase shared_buffers
   • Increase effective_cache_size
   • Optimize query patterns

4. High rollback rate >5%:

   • Review application logic
   • Optimize transaction boundaries
   • Consider READ COMMITTED isolation level

Current Status: ✅ No Tuning Required

All metrics are well within acceptable ranges. Monitor production load and revisit if needed.
