SQL Server Performance Tuning

Stop guessing. Our certified SQL Server DBAs diagnose performance bottlenecks using wait statistics, execution plan analysis, and Query Store — then fix them permanently.

Common SQL Server Performance Challenges We Fix

Slow Query Execution

Missing indexes, bad execution plans, parameter sniffing issues, and implicit conversions killing query performance.

High CPU & Blocking

Inefficient queries consuming excess CPU, lock contention, and blocking chains causing cascading timeouts.

TempDB & Memory Pressure

TempDB contention under concurrency, memory grant waits, and buffer pool pressure degrading throughput.

I/O Bottlenecks

Slow data file I/O, log file contention, and fragmented indexes causing excessive disk reads.

Our Performance Tuning Methodology

A systematic, data-driven approach to SQL Server performance optimization.

Performance Audit

Baseline capture of top wait types, heaviest queries, and resource consumption patterns.

Query Store
Extended Events
DMVs

Execution Plan Analysis

Identify parameter sniffing, bad estimates, missing joins, and plan regressions.

SQL Server Management Studio
SentryOne Plan Explorer

Index Optimization

Add, consolidate, or rebuild indexes; remove unused indexes to reduce write overhead.

Missing Index DMVs
Index Usage Stats
Fragmentation Analysis

Server Configuration

Right-size MAXDOP, parallelism thresholds, max server memory, and TempDB layout.
