 ## Performance
 
 I use a 2-layer map to cache all lsp progress messages, thus transforming the
-**O(n \* m)** time complexity calculation to almost **O(1)**.
+**O(N \* M)** time complexity calculation to almost **O(1)**.
 
-> **n** is active lsp clients count, **m** is token count of each lsp client.
