### Is Powerlevel10k fast to load?
The short answer is no. The amount of time it takes for Powerlevel10k to render the first prompt
is in the same ballpark as for Powerlevel9k.
The amount of time it takes for Powerlevel10k to render the first prompt is singnificantly higher
than for the subsequent prompts. In comparison to other ZSH themes, Powerlevel10k loading latency
is unremarkable. Powerlevel10k is neither fast nor slow to load.

If your workflow requires that you open a terminal tab, type a command or two and close the tab,
Powerlevel10k isn't the best choice. Powerlevel10k is optimized for long-lived ZSH sessions.
*Note: Powerlevel10k startup latency can be reduced by about 15% by compiling its source files with
`zcompile`.*
### Does Powerlevel10k always render exactly the same prompt as Powerlevel9k given the same config?
