## How fast is it?
|
|
|
|
|
|
|
|
|
|
Powerlevel10k renders prompt about 50 times faster than powerlevel9k/master (stable version) and
|
|
|
|
|
about 15 times faster than powerlevel9k/next (beta version).
|
|
|
|
|
Powerlevel10k renders prompt between 10 and 100 times faster than powerlevel9k.

Here's how the prompt looked like during benchmarking.

|
|
|
|
|
|
It was identical in Powerlevel10k and Powerlevel9k. Even though Powerlevel10k can dynamically
|
|
|
|
|
switch to async prompts, it wasn't happening here because latencies were low. Prompts with both
|
|
|
|
|
themes were essentially synchronous with every prompt having up-to-date git info.
|
|
|
|
|
|
|
|
|
|
_This table used to have another column for Linux kernel git repo, which is massive. It's
|
|
|
|
|
been removed because it's not a fair comparison. Powerlevel10k automatically detects that
|
|
|
|
|
fetching git status is slow and switches to async prompt generation, which allows it to
|
|
|
|
|
achieve 2 ms prompt latency but not all its prompt have up-to-date git info. Those that don't,
|
|
|
|
|
have vcs segment greyed out._
