# Benchmarks
|
|
|
|
## vtebench
|
|
|
|
All benchmarks are done using [vtebench](https://github.com/alacritty/vtebench):
|
|
|
|
```sh
|
|
vtebench -h $(tput lines) -w $(tput cols) -b 104857600 alt-screen-random-write > ~/alt-random
|
|
vtebench -c -h $(tput lines) -w $(tput cols) -b 104857600 alt-screen-random-write > ~/alt-random-colors
|
|
vtebench -h $(tput lines) -w $(tput cols) -b 10485760 scrolling > ~/scrolling
|
|
vtebench -h $(tput lines) -w $(tput cols) -b 104857600 scrolling --fill-lines > ~/scrolling-filled-lines
|
|
vtebench -h $(tput lines) -w $(tput cols) -b 10485760 unicode-random-write > ~/unicode-random
|
|
```
|
|
|
|
They were "executed" using [benchmark.py](../scripts/benchmark.py),
|
|
which will load each file into memory, and then print it to the
|
|
terminal. This is done **20** times for each test. Then it calculates
|
|
the _mean_ and _standard deviation_ for each test.
