Performance and Benchmarks

Circom

In summary:
Both native witness generation and proof generation are generally faster than snarkjs in the browser, with potential speed improvements of up to 20 times.
However, performance varies across different circuits. We recommend developers benchmark their custom circuits before selecting tools for app development.

Note that the iPhone 15 Pro crashes when running the RSA circuit due to the large memory requirements. The circuit needs around 5GB of memory to run, while the iPhone 15 Pro usually limits the application memory usage to 3GB.
