Performance analysis

For over 15 years, we've been assisting companies in constructing high-performance websites, mobile applications, and enterprise systems.

Mitigating the risks of software crashes and failures under heavy loads.
Uncovering your application's peak performance capabilities.
Determining your hardware resource requirements for cost reduction.
Identifying performance-limiting bottlenecks.

Ask yourself

How happy are the system owners with its present performance?

Do performance failures or service denials occur in the depths of your information system?
Have you identified their root causes?
Do you have solutions to rectify these issues?

Get the answers

Performance analysis of information systems is one of our primary areas of expertise, and we keep developing in this domain.

Analyze your system's performance

We leverage our extensive experience and cutting-edge technology to assist you in solving your system issues.

Whether it involves analyzing your system’s performance during issue occurrences or conducting load testing when replicating the problem is challenging, we’re dedicated to pinpointing all performance concerns.

Identify bottlenecks

Our aim is to identify bottlenecks causing system issues and provide actionable recommendations for their resolution.

Learn more about the process

A well-organized process is fundamental for success.

Plan and prioritize

In the initial phase, we interview the technical team of your project to identify issues and their conditions.

Our aim is to evaluate if the problem is reproducible and gather details about your monitoring tools, system architecture, and business logic.

Reproduce the problem

  • The problem is reproducible: If the issue is easily reproducible and can be tracked, we access your product and analyze it with our monitoring tools.
  • The problem is not reproducible: If it can’t be replicated, we create a test environment and attempt to reproduce the issue under load.

Correlation analysis

Correlation analysis involves comparing important data and analyzing them using various monitoring tools. For instance, if we are aware that an issue arises at specific intervals, we investigate the events happening at various system levels during those stretches of time.

The primary objective of correlation analysis is to pinpoint the root cause of the problem.

Investigate failures

In the next step, we provide you with comprehensive troubleshooting recommendations based on our analysis.
Alongside these, you’ll receive a detailed report summarizing our findings and insights.

Our aim is to empower you with the knowledge and guidance needed to resolve any performance issues and optimize your system for peak performance.

Creation of the Load Testing Profile
Jun 27, 2020

Load profile is a set of operations and their intensity, chosen in such a way, that together they create a load comparable to the production load. Load testing preparation is one of the most important steps in the load testing. An incorrect load profile generates testing results that are not related to the production. We […]
