 ## 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 are benchmark results obtained with
 [zsh-prompt-benchmark](https://github.com/romkatv/zsh-prompt-benchmark) on Intel i9-7900X
 running Ubuntu 18.04.

 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._
