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.
A mere 3-second delay in website loading can cause 53% of visitors to leave. Slow-loading sites cost retail businesses a staggering $2.6 billion yearly. Even a tiny 100ms delay can slash revenue by 1%. But it’s not just speed—browser choice matters too, with Google Chrome outperforming Microsoft Edge. Key metrics like bounce rate and conversion rate are vital for assessment. To enhance website speed, implement strategies like caching, compression, CDNs, optimize images and assets, and reduce server response times.
However, e-commerce testing is no easy feat. You need to have extensive knowledge of e-commerce development to obtain optimal results. In this article, we discuss the top considerations that make the e-commerce testing process simpler.
