The Client
The client is a US-based used car selling company with a nationwide buyer network. Its platform provides sellers with instant offers for their cars using price prediction algorithms and real-time bids from a network of licensed buyers.
The Challenges
Maintaining Performance Under High User Loads
The client's website was mission-critical and needed to support thousands of users generating offers while maintaining stable performance and minimal response times.
4,000–5,000 Daily Users
The website handled thousands of users generating offers for their cars each day.
High Concurrent Usage
The website needed to support many users at the same time without affecting the user experience.
Complex Infrastructure
Multiple servers, file servers, databases, and web services made system behavior difficult to predict under real-time load.
Scalability Requirements
The application needed to maintain performance as user demand increased.
No Separate Test Environment
Without an independent performance testing environment, test results may be inaccurate.
Prepare Your Application for Real-World Traffic
Identify performance bottlenecks, test system capacity, and improve application reliability before issues affect users.
The Solution
A Structured Approach to Performance Engineering
Maruti Techlabs studied the client's business processes, infrastructure, and software development lifecycle before defining performance goals and identifying potential bottlenecks.
Established success criteria and performance metrics based on the client's requirements.

Frequently Asked Questions
Performance testing helps determine how an application behaves under expected and increased user loads. It can reveal bottlenecks, scalability limitations, and response-time issues before they affect users.
Performance tests should replicate relevant production conditions, including infrastructure, workloads, user volumes, and test data. In this project, we configured an independent performance testing environment to align with production.
Common performance metrics include response time, throughput, resource utilization, error rates, and system capacity. Define specific success criteria based on the application's requirements and expected workload.
By gradually increasing the load and monitoring system behavior, testing teams can identify when response times increase, errors occur, or infrastructure resources become constrained. This helps teams understand how the application responds as demand grows.
Realistic test data helps create scenarios that better represent actual application usage. In this project, the QA team prepared performance test data according to the defined scripts and scenarios before executing the tests.
