If we speak about commercial load testing tools, we see rather a shrinking market and not too much innovation recently. Microfocus acquired both LoadRunner from HP and Silk Performer (as a part of Borland). At one point SOASTA gathered a great team of performance experts – almost all left the company by now.

Many of our users are performance engineers using Cloud Automation Quality Gates to automate the analysis of their performance and load tests – saving hours of analysis time for each test they run. You run load tests monitored with Dynatrace and you want to automatically validate to eliminate the manual analysis effort.

At some point you'll be given permission to "focus on performance" and after many more hours, the website will be fast again. What if there was a way that you could prevent performance from degrading in the first place? Some sort of performance gateway that only allows changes to production code if they meet performance requirements?
