### Is it really fast?
Yes.

Benchmark results obtained with
[zsh-prompt-benchmark](https://github.com/romkatv/zsh-prompt-benchmark) on an Intel i9-7900X
running Ubuntu 18.04 with the config from the demo.
| Theme | Prompt Latency |
|---------------------|---------------:|
| powerlevel9k/master | 1046 ms |
| powerlevel9k/next | 1005 ms |
| **powerlevel10k** | **8.7 ms** |
Powerlevel10k is over 100 times faster than Powerlevel9k in this benchmark.
In fairness, Powerlevel9k has acceptable latency when given a spartan configuration. If all you need
is the current directory without truncation or shortening, Powerlevel9k can render it for you in
17 ms. Powerlevel10k can do the same 30 times faster but it won't matter in practice because 17 ms
is fast enough (the threshold where latency becomes noticeable is around 50 ms). You have to be
careful with Powerlevel9k configuration as it's all too easy to make prompt frustratingly slow.
Powerlevel10k, on the other hand, doesn't require trading latency for utility -- it's virtually
instant with any configuration. It stays well below the 50 ms mark, leaving most of the latency
budget for other plugins you might install.
Yes. See [zsh-bench](https://github.com/romkatv/zsh-bench) or a direct comparison with
[Powerlevel9k](https://asciinema.org/a/NHRjK3BMePw66jtRVY2livHwZ) and
[Spaceship](https://asciinema.org/a/253094).
