# Uncompromising performance

When you hit _ENTER_, the next prompt appears instantly. With Powerlevel10k there is no prompt lag.
If you install Cygwin on Raspberry Pi, `cd` into a Linux Git repository and activate enough prompt
segments to fill four prompt lines on both sides of the screen... wait, that's just crazy and no
one ever does that. Probably impossible, too. The point is, Powerlevel10k prompt is always fast, no
matter what you do!

Note how the effect of every command is instantly reflected by the very next prompt.

| Command                       | Prompt Indicator |                                                               Meaning |

| `timew start hack linux`      |  `🛡️ hack linux`  |      time tracking enabled in [timewarrior](https://timewarrior.net/) |
| `touch x y`                   |       `?2`       |                                     2 untracked files in the Git repo |
| `rm COPYING`                  |       `!1`       |                                     1 unstaged change in the Git repo |
| `echo 3.7.3 >.python-version` |    `🐍 3.7.3`     | the current python version in [pyenv](https://github.com/pyenv/pyenv) |

Other Zsh themes capable of displaying the same information either produce prompt lag or print
prompt that doesn't reflect the current state of the system and then refresh it later. With
Powerlevel10k you get fast prompt _and_ up-to-date information.
