FAQPage Schema

How do I find N+1 queries and Big-O hot paths in my codebase?▼

To find N+1 queries and Big-O hot paths, a performance review analyzes your codebase for algorithmic efficiency and database design issues, reporting findings with a confidence score of 7/10 or higher.

What is a performance fitness score and how does it assess scalability?▼

A performance fitness score quantifies scalability readiness by evaluating your code across algorithmic efficiency, database design, caching strategy, resource utilization, and data pipeline efficiency to identify potential bottlenecks.

How do I check if my API endpoints can handle anticipated traffic before deploying?▼

To check if API endpoints can handle traffic before deployment, run a scalability analysis to evaluate readiness for horizontal scaling and pinpoint resource utilization bottlenecks that might degrade response times under load.

Can I run a performance review on a specific module like user authentication?▼

Yes, you can run a performance review on specific modules like user authentication to target inefficient algorithms, database queries, and resource utilization issues within that particular area of your project.

What's the best way to evaluate caching strategy and database design for optimization?▼

To evaluate caching strategy and database design for optimization, use a performance analysis tool that quantifies bottlenecks and scores your codebase's fitness across these specific scalability dimensions.
