IVR
IVR performance testing
It serves as a potential bottleneck, particularly during surges in call volumes triggered by promotions or weather changes.
Given the prevalence of automated operations, we specialize in assessing how adeptly your IVR systems manage diverse loads during peak times.

Stats don’t lie
The U.S. IVR market, valued at $1.4 billion in 2021, represents 31.4% of the global market share.

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.
Modern contact centers are often complex systems that involve close interaction between IVR, customer relation management (CRM), and many other services. Therefore, besides testing the performance of IVR itself and telephone communication channels, PFLB offers comprehensive testing services that allow you to evaluate the performance of both overall and individual services and to identify the influence of system components on each other.
Around the world, JMeter and LoadRunner remain some of the most popular tools for load testing. These are truly excellent tools and most performance engineers use them.
When choosing load testing tools the main question is whether the tool supports all the required protocols? When it comes to HTTP, the selection of tools is enormous, including excellent cloud solutions that make it possible to create a load simultaneously from different points on the planet. For less common protocols the number of suitable tools shrinks considerably. In these cases, the indisputable leader is LoadRunner, an HP product and the de facto standard in the enterprise segment.
