# intl-measurements

This repository is a sub-project of ICU4X project and contains a harness and implementations of small benchmarks for measuring performance, memory and size differences between various implementations of ICU.

The main goal of this project is to establish a reasonable framework for comparing those measurements across multiple implementations and validate a claim that ICU4X is not slower, doesn't use more memory and doesn't take more space than a comparable alternatives.

# Tests

At the moment the harness is focused on measuring performance between:

* ICU4X 0.1

* ICU4C 67 (using C++ apps)

* ICU4C 67 (via `rust_icu`)

* ICU4C 67 (via FFI)

* A set of earlier Rust implementations of components such as `intl_pluralrules`, `unic_locale`, and `unic_datetime`

The aim is to make it easy to compare different backends for similar basic operations and minimize noise in data.

The tests can be launched via `stand-alone` binaries, or in case of all Rust apps via `criterion` benchmark.

# Current results (as of October 19 2020)

Specs:

* Dell Tower 5820

  * Intel(R) Xeon(R) W-2155 CPU @ 3.30GHz x20

  * 32 GB RAM

* **C++**: GCC 10

* **Rust**: 1.47

* **ICU4C**: 67

* **ICU4X**: icu4x 0.1

Sample: 956 locale strings provided to MozLocale constructor during fresh-profile startup of Firefox Nightly on Oct 21st 2019.
