This is the beginning of a basic benchmarking suite. So far it doesn't do much. These use criterion.rs for testing.
There are some benchmarks for the engine itself to track changes over time and
comparison benchmarks against handlebars, liquid and tera.
To run the benchmarks:
$ cargo bench
These are the results run on a MacBook Pro 16" 2021:
cmp_compile/handlebars time: [46.856 µs 46.895 µs 46.943 µs]
cmp_compile/liquid time: [76.993 µs 77.069 µs 77.166 µs]
cmp_compile/minijinja time: [4.2695 µs 4.2790 µs 4.2881 µs]
cmp_compile/tera time: [85.535 µs 85.602 µs 85.685 µs]
cmp_render/askama time: [1.6896 µs 1.6933 µs 1.6971 µs]
cmp_render/handlebars time: [6.2611 µs 6.2645 µs 6.2683 µs]
cmp_render/liquid time: [12.013 µs 12.030 µs 12.048 µs]
cmp_render/minijinja time: [4.9891 µs 4.9972 µs 5.0069 µs]
cmp_render/tera time: [8.1737 µs 8.1826 µs 8.1925 µs]
Note that Askama compiles templates as part of the Rust build process and uses static typing, as such it does not have a compile time benchmark.
