PFLB Service

Core banking

Core banking performance testing

Core banking systems are the linchpin of financial institutions’ IT infrastructure, and system failures can incur substantial losses, necessitating load testing in many banks.
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

Failed payments are estimated to cost the global economy approximately $118.5 billion annually.

This estimation is based on a study, which involved responses from 240 organizations across the banking, financial, fintech, and corporate sectors.
The cost of failed payments varies significantly based on the type and size of the organization.

The average bank spent a little over $360,000 in 2020 on failed payments, including fees, labor, and costs related to customer attrition.
The average non-bank financial institution (NBFI) spent nearly $220,000.

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.
Corporations spent somewhat less, with averages just over $200,000.

When you might need it

At PFLB, we provide an extensive array of testing services, such as post-merger/acquisition validation, ongoing performance testing for system updates, performance enhancement, and go-live assurance.

Post-merger/acquisition validation

This type of testing is imperative after a merger or acquisition.
It ensures that the newly integrated infrastructure aligns seamlessly with your business objectives and doesn’t hinder productivity.

Ongoing performance testing for system updates

In the dynamic landscape of core banking systems, regular performance testing is indispensable.
It ensures that your systems maintain peak productivity with each update or modification.

Performance enhancement

Sometimes, your core banking system’s performance may not meet expectations, and immediate action is required.
This includes identifying and eliminating bottlenecks, optimizing resources, and fine-tuning processes to enhance overall efficiency.

Go-live assurance

The successful launch of new systems is critical to guarantee their proper functionality.
Go-live assurance involves a series of tests and validations to ensure that the new system operates smoothly and without any hitches.

Sample report

You will receive a comprehensive report that summarizes all the issues uncovered during testing.
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.

We configure the test project and infrastructure in various ways, such as in the client’s DMZ, using the PFLB cloud, or a hybrid approach. In the hybrid model, we leverage the PFLB platform and oversee testing from our cloud, offering you cloud access via our website. Meanwhile, the load generators are positioned on your local network.
This setup allows you to easily rerun tests and obtain reports for independent analysis of new application releases.
We will provide you with a report on the bottleneck analysis and recommendations for optimization.
If our objective was to implement in CI/CD, the outcome will be a tailored integration into the development pipeline.

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.
