Study Notes

Flow or FloGo, an open-source, microservice-based blockchain application, had problems with its performance when subjected to a higher load.
To figure out the root cause of the problem, the developers used performance profiling to identify which parts of the application were causing the bottleneck.
By tracing the traffic between different nodes, they were able to identify that the consensus nodes were causing the bottleneck.
Performance characterization includes mapping to understand the part of the application that needs to be investigated, and generating a flame graph to show where the application is spending time.
The access node is the most non-performant part of the application and has a high CPI.
To improve performance, the access node should be investigated and optimized.
