# UTF-8 Benchmark
The idea is to benchmark several utf-8 aspects of the Haskell Text package. Namely utf-8 encoding/decoding and various unicode casing operations. Hopefully, we'll find ways to improve text's performance.
For the time being, we're comparing the Text implementation with the C ICU one. In the future I also plan to test it against C++ Boost and the Rust stdlib.

# Findings
## UTF-8 Decoding
```
hyperfine ./haskell-read-utf8 ./icu-read-utf8
Benchmark #1: ./haskell-read-utf8
Time (mean ± σ): 23.3 ms ± 0.9 ms [User: 14.9 ms, System: 8.3 ms]
Range (min … max): 22.0 ms … 26.1 ms 111 runs
Benchmark #2: ./icu-read-utf8
Time (mean ± σ): 12.5 ms ± 0.8 ms [User: 7.6 ms, System: 4.9 ms]
Range (min … max): 11.5 ms … 16.1 ms 176 runs
Summary
'./icu-read-utf8' ran
1.85 ± 0.14 times faster than './haskell-read-utf8'
