Query Plan Analysis for .NET Workloads

Slow endpoints in .NET systems are frequently caused by inefficient query plans—parameter sensitivity, missing statistics, suboptimal join strategies, or ORM-generated SQL that doesn’t match the database’s optimal access paths. Teams often experience rising p95 latency, intermittent timeouts, CPU spikes in the database, and “it works on my machine” behavior across environments.

DevionixLabs solves this by performing deep query plan analysis specifically for .NET workloads. We correlate application behavior with database execution plans to pinpoint why the optimizer chooses a plan that’s slower than expected. For ORM-driven systems, we also examine how query shapes, parameterization, and tracking settings influence the generated SQL and resulting plans.

What we deliver:
• A query plan diagnosis that identifies the exact plan operators and root causes behind latency spikes
• Actionable recommendations for SQL, indexing, parameter handling, and ORM query shaping
• A validation report showing before/after plan changes and measurable improvements in endpoint performance

Our analysts focus on the failure modes common to .NET systems: parameter sniffing, plan regression after deployments, mismatched parameter types, and statistics drift. We provide guidance that your developers can implement—such as query rewrites, safer parameter strategies, and EF Core-specific adjustments—while keeping changes aligned with database best practices.
