# Line Count

Timings for performing line counts.

## `wc -l` - Word Count
```sh
time wc -l < /tmp/lines_5m.csv
# => 5000000
# => 0.86s user 0.26s system 99% cpu 1.121 total

## Node stream-stat
https://github.com/peterwmwong/stream-stat

```sh
time node index-pipe.js < /tmp/lines_5m.csv > /dev/null
# => 1,405,353,984 bytes [ 686,208 kb/sec ] | 4,986,019 lines [ 2,493,009 lines/sec ]
# => 2.17s user 0.95s system 110% cpu 2.812 total

# Rust `io.lines()`

This does not return the correct byte count.

```sh
time ./lines < /tmp/lines_5m.csv > /dev/null
# => num_lines: 5000000, num_bytes: 1404473763
# => 0.75s user 0.34s system 99% cpu 1.100 total
```

## Rust `io.read_line()`

```sh
time ./read_line < /tmp/lines_5m.csv > /dev/null
# => num_lines: 5000000, num_bytes: 1409473763
# => 0.48s user 0.32s system 99% cpu 0.800 total
```
