 Powerlevel10k uses the same configuration options as Powerlevel9k and produces the
 same results. It's simply faster. There is no catch.
 
 If you are on Linux or WSL, consider enabling [gitstatus](https://github.com/romkatv/gitstatus)
-plugin for massive performance improvement in vcs/prompt segment. It works well with Powerlevel10k.

 ## How fast is it?
 
-Powerlevel10k with [gitstatus](https://github.com/romkatv/gitstatus) renders prompt 5+ times
-faster than Powerlevel9k. In some cases it can be over 10 times faster. When using Linux,
-you should expect less than 50ms prompt latency in most cases, about 100ms in large git
-repos and 200ms in huge repos such as Linux kernel. To get comfortable upper bound on
-latency in any repo, set `GITSTATUS_DIRTY_MAX_INDEX_SIZE=4096`. It'll disable dirty file
-scanning in repos with over 4k files. This should give you under 100ms prompt latency
-everywhere.
+Powerlevel10k with [gitstatus](https://github.com/romkatv/gitstatus) renders prompt about
+10 times faster than powerlevel9k/master (stable version) and about 4 times faster than
+powerlevel9k/next (beta version). Powerlevel10k is faster than Powerlevel9k even without
+[gitstatus](https://github.com/romkatv/gitstatus) but the difference isn't as dramatic.
+

 ## What's the catch?
 
-Really, there is no catch. It's the same prompt with the same flexibility and literally the
