Financial Services Performance Optimization
Project Overview
Led a comprehensive performance tuning initiative for a major financial institution's high-frequency trading platform, addressing critical performance bottlenecks that were impacting trading operations and revenue.
Project Scope & Challenges
This project involved several key challenges that required innovative solutions:
- Critical trading queries taking 15+ seconds causing competitive disadvantage
- Database server reaching capacity limits during peak trading hours
- Complex queries involving multiple large tables with poor performance
- Need for real-time performance monitoring and alerting
- Minimal downtime window for implementing optimizations
Technical Implementation
Performance Analysis: Conducted comprehensive analysis using SQL Server Profiler, Query Store, and custom monitoring tools to identify bottlenecks and resource constraints.
Index Optimization: Redesigned indexing strategy with columnstore indexes for analytical queries and optimized B-tree indexes for transactional operations.
Query Rewriting: Rewrote critical queries using advanced SQL techniques including window functions, CTEs, and optimized join strategies.
System Tuning: Optimized SQL Server configuration settings including memory allocation, parallelism, and I/O subsystem parameters.
Results & Impact
- Reduced average query response time from 15 seconds to under 2 seconds (85% improvement)
- Increased system throughput by 300% during peak trading hours
- Generated additional $2.3M in revenue in first quarter post-optimization
- Eliminated need for expensive hardware upgrades
- Implemented proactive monitoring preventing future performance issues
