Solving a Performance Problem of a Mission Critical SaaS Application with ANTLR


When you offer a mission critical service that must always be up and running, the robustness of your service is of critical importance. Recently, OpsGenie overcame a performance problem that threatened our mission critical application, and we wanted to share this experience with others. This experience involved identifying and analysing our problem, evaluating possible solutions and implementing the selected solution. In the end, we speed up a critical capability by x25, reduced overall memory and CPU consumption notably and avoided random crashes.
