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
