# Description
This speeds up writing messages to the plugin, because otherwise every
individual piece of the messages (not even the entire message) is
written with one syscall, leading to a lot of back and forth with the
kernel.
I learned this by running `strace` to debug something and saw a ton of
`write()` calls.
```nushell
# Before
1..10 | each { timeit { example seq 1 10000 | example sum } } | math avg
269ms 779µs 149ns
# After
> 1..10 | each { timeit { example seq 1 10000 | example sum } } | math avg
39ms 636µs 643ns
```
