AWS Lambda CPU and Memory Profiling (Node.js)

Profiling cloud applications Performance profiling is essential for optimizing and fixing application’s resource consumption, response time and failures. A performance issue without an execution profile is like an error without a stack trace. It will lead to a lot of manual work to get to the root cause. Profiling cloud applications and functions such as […]

Continuous Performance Profiling

Computational complexity requirements The difference between exponential, linear, logarithmic and constant execution time of a program is critical for various use cases. Even if an algorithm is purposely designed to satisfy a certain complexity class, there are multiple reasons why it might not. An underlying library, OS or even hardware can be the root cause […]
