This document provides an overview of how to analyze compiled circuits and extract statistical data for performance evaluation in Concrete. These statistics help identify bottlenecks and compare circuits.
Basic operations
Concrete calculates statistics based on the following six basic operations:
Clear addition:x + y where x is encrypted and y is clear
Encrypted addition:x + y where both x and y are encrypted
Clear multiplication:x * y where x is encrypted and y is clear
Encrypted negation:-x where x is encrypted
Key switch: A building block for table lookups
Packing key switch: A building block for table lookups
Programmable bootstrapping: A building block for table lookups
Displaying statistics
You can print all statistics using the show_statistics configuration option:
Each of these properties can be directly accessed on the circuit (e.g., circuit.programmable_bootstrap_count).

Imagine you have a neural network with 10 layers, each of them tagged, you can easily see the number of additions and multiplications required for matrix multiplications per layer:
