Performax has been pivotal to our SaaS cloud infrastructure & databases running smoothly for the past 7 years. We partnered with Performax to build and load test a prototype of our Internet of Things on Wheels SaaS at AWS in 2013. We decided to keep them as on as our cloud IT team to build out and operate a scalable, secure, and fault tolerant SaaS infrastructure which now serves over 100,000 vehicles daily. 

Over the years, Performax has worked seamlessly with our development organization to test, model, and improve our SaaS performance and cost per vehicle. Their automation and standardization of infrastructure allowed us to sustain a rapid deployment cadence and high availability. They continuously evaluated new cloud and 3rd party services for price/performance and pioneered creative solutions such as a low-cost Disaster Recovery as a Service based on Zadara Storage as a Service.

Having team members in both Europe and the US helped Performax provide support around the clock for our growing SaaS and the overall availability of our SaaS has been outstanding. Their commitment to our success reduced our risk and allowed us to realize the flexibility, costs savings, and reliability expected from AWS. I highly endorse Performax’s expertise and commitment to customer success and recommend them for building and operating SaaS infrastructures & databases.

Performax was instrumental in helping us get our OpenSTA implementation off the ground. Bernie's method of using the actual website during the training sessions produced re-usable assets, which is a very effective way of learning the tool. With the training and Bernie's follow-up guidance and support we were able to refine our scripts and attain performance metrics very quickly. As we progressed through our capacity testing process Bernie continued to help and provided valuable feedback and insight. I would recommend Bernie and Performax to anyone seeking guidance with OpenSTA specifically or with their performance test project in general.

We searched for a load testing service provider with the experience, tools, and methodology necessary to ensure our new application delivered the highest level of performance, stability, and availability. We chose Performax based on their reputation, technical depth, and responsiveness. Performax's expertise and team approach kept our performance characterization project focused and on schedule. The recommendations made for improving production cluster capacity and availability have been implemented and their capacity planning guidelines will help us keep ahead of demand as our customer base grows. Performax is a pleasure to work with and I highly recommend using their services.

We wanted to use OpenSTA to load test our new web service but were concerned about the learning curve, support, and its ability to emulate our compressed SOAP messages. Performax modified OpenSTA to use our data compression methods and demonstrated it's feasibility before starting the project. Their commitment to our success reduced our risk and allowed us to realize the flexibility and cost savings expected from using an open source tool. Bernie Velivis at Performax is one of the best OpenSTA resources around and I highly endorse his expertise and commitment to customer service.

We employed Performax on several performance optimization efforts at Kaplan and were very satisfied with the results.  Bernie is diligent, very thorough, and explained the what's and how's of performance tuning.  With the results of each effort, each system in question was able to prepare for upcoming scalability in an educated manner.
