Core banking
Core banking performance testing
We bring significant expertise in load testing components such as loan and deposit servicing, payment transactions, ATM networks, card processing, and Internet banking.
Our proficiency extends to both retail and investment banks, with over half our projects dedicated to this area.

Stats don’t lie
This estimation is based on a study, which involved responses from 240 organizations across the banking, financial, fintech, and corporate sectors.
The average bank spent a little over $360,000 in 2020 on failed payments, including fees, labor, and costs related to customer attrition.
Averages also differ based on the size of organizations, ranging from below $40,000 for companies with revenue below $10 million to over $20 million for the largest banks globally.
When you might need it
Post-merger/acquisition validation
It ensures that the newly integrated infrastructure aligns seamlessly with your business objectives and doesn’t hinder productivity.
Ongoing performance testing for system updates
It ensures that your systems maintain peak productivity with each update or modification.
Performance enhancement
This includes identifying and eliminating bottlenecks, optimizing resources, and fine-tuning processes to enhance overall efficiency.
Go-live assurance
Go-live assurance involves a series of tests and validations to ensure that the new system operates smoothly and without any hitches.
What we could offer you
We identify nodes prone to higher loads, create a capacity plan, and evaluate the existing system’s ability to handle business expansion, pinpointing potential bottlenecks.
This ensures the system’s reliability and performance under varying workloads.
Our team also offers training and support to assist your development teams in adopting best practices for performance testing.
Whether it’s synthetic data generation or data masking, we offer tailored solutions for a seamless testing experience.

Sample report
This report includes visualized metrics and recommendations for performance optimization. Each instance of resource overconsumption by the application will be thoroughly detailed, including its business impact, the responsible component, and the specific system section involved.
This approach allows you to identify the operations utilizing the most resources and isolate the component and code section responsible for the issue.

This setup allows you to easily rerun tests and obtain reports for independent analysis of new application releases.

PFLB has been Tinder’s load testing provider for over 5 years, and it is a true pleasure working with them. They managed the entire performance engineering process for our app releases, helping us fix tons of performance issues. I highly recommend PFLB as a reliable vendor.


PFLB’s testing team helped us successfully complete the FDA regulations with a great test coverage for the computer system validation (CSV) process at Illumina. I highly recommend Yuri Kovalov and his team—they’re top-notch professionals in performance and load testing.


We smoothly moved over 30 JMeter projects to PFLB, and it’s been a total game changer. It’s given our team of 50+ remote performance engineers the ability to handle large-scale load tests every day with real ease.


PFLB did benchmarking tests on our database storage engine under standard and uncommon conditions, using specialized tools. Their analysis gave us valuable insights and recommendations to boost our product’s performance. I highly recommend PFLB to anyone looking for an expert performance testing company.


PFLB was willing to work with a very small solopreneur without an enormous investment in capital. Their prices were reasonable and provided me with notable improvements to my php performance.


It was a pleasure working with PFLB, and I’d recommend them for performance testing. They quickly got up to speed with our complex software architecture and were super productive in setting up our load test environment in the cloud. They were really dedicated to improving our product with their strong expertise in performance optimization.


I was highly satisfied working with PFLB. They’re a fantastic one-stop shop for software performance, with everything you need—their platform and skilled engineers. I’ve used them three times to load test the College Board software before big updates, and it all went smoothly. Plus, I love that they store all the testing data, so we can track performance capacity over time.
Our client’s bank was absorbing other banks, and the number of individual clients was growing. The system was not ready for expansion or integration. The owners started to suspect bottlenecks when problems with paying salaries to corporate clients’ employees arose. As a result, in the next pay period, the load on the system increased dramatically, and the system got overloaded. People did not get their salaries in time, as the system crashed.
PFLB offers expertise services on automated testing of the core Banking System improving the quality of the product and allowing the customers to keep time frames and costs under control.
As a rule, software testing has a unified set of principles and standards that stay true for all industries. However, there are a few areas that require extra dedication and commitment as well as attention to security issues. In the banking domain it is especially necessary. If you don’t know how to approach banking application […]
