 ## ⚡ Performance
 
-This package offer better performance than Python version (3 times faster, than MYPYC version of charset-normalizer, 6 times faster than usual Python version).
-However, in comparison with `chardet` and `chardetng` packages it is slower but more accurate (I guess because it process whole file chunk by chunk). 
+This package offer better performance than Python version (4 times faster, than MYPYC version of charset-normalizer, 8 times faster than usual Python version).
