# Benchmarks

Due to their nature, homomorphic operations are obviously slower than their clear equivalent. In what follows, some timings are exposed for basic operations. For completeness, some benchmarks of other libraries are also given.

All the benchmarks had been launched on an AWS m6i.metal with the following specifications: Intel(R) Xeon(R) Platinum 8375C CPU @ 2.90GHz and 512GB of RAM.

## Boolean

This measures the execution time of a single binary boolean gate.

### tfhe.rs::boolean.

| Parameter set         | concrete-fft | concrete-fft + avx512 |
| --------------------- | ------------ | --------------------- |
| DEFAULT\_PARAMETERS   | 8.8ms        | 6.8ms                 |
| TFHE\_LIB\_PARAMETERS | 13.6ms       | 10.9ms                |

### tfhe-lib.

| Parameter set                                    | fftw   | spqlios-fma |
| ------------------------------------------------ | ------ | ----------- |
| default\_128bit\_gate\_bootstrapping\_parameters | 28.9ms | 15.7ms      |

### OpenFHE.

| Parameter set | GINX  | GINX (Intel HEXL) |
| ------------- | ----- | ----------------- |
| STD\_128      | 172ms | 78ms              |
| MEDIUM        | 113ms | 50.2ms            |

## Shortint

This measures the execution time for some operations and some parameter sets of shortint.

### tfhe.rs::shortint.

This uses the concrete-fft + avx512 configuration.

| Parameter set               | unchecked\_add | unchecked\_mul\_lsb | keyswitch\_programmable\_bootstrap |
| --------------------------- | -------------- | ------------------- | ---------------------------------- |
| PARAM\_MESSAGE\_1\_CARRY\_1 | 338 ns         | 8.3 ms              | 8.1 ms                             |
| PARAM\_MESSAGE\_2\_CARRY\_2 | 406 ns         | 18.4 ms             | 18.4 ms                            |
| PARAM\_MESSAGE\_3\_CARRY\_3 | 3.06 µs        | 134 ms              | 134 ms                             |
| PARAM\_MESSAGE\_4\_CARRY\_4 | 11.7 µs        | 854 ms              | 945 ms                             |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.zama.org/tfhe-rs/tfhe-rs/0.1-1/getting-started/benchmarks.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
