# 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.

[^1]: Alacritty is actually **really** slow at rendering this (whether
|
|
it is fallback fonts in general, emojis, or something else, I
|
|
don't know). I believe the reason it finishes the benchmark so
|
|
quickly is because it reads from the PTY in a separate thread,
|
|
into a larger receive buffer which is then consumed by the main
|
|
thread. This allows the client program to write its output much
|
|
faster since it is no longer stalling on a blocked PTY. This means
|
|
Alacritty only needs to render a couple of frames since it can
|
|
reach the final VT state almost immediately. On the other hand,
|
|
`cat`:ing the `unicode-random` test file in an endless loop, or
|
|
just manually scrolling up after the benchmark is done is
|
|
**slow**, which besides being felt (input lag), can be seen by
|
|
setting `debug.render_timer = true` in `alacritty.yml`.
