-## Performance
-
-For single-threaded use cases, enabling the KleidiCV OpenCV HAL is likely to
-provide a performance boost for the functions that it implements.
-The same is true for multi-threaded use cases, with the exception of the
-following functions:
-* dilate
-* erode
-* GaussianBlur
-* resize
-* sepFilter2D
-* Sobel
-* transpose
-Multithreading is planned for these functions in KleidiCV but at present they
-are single-threaded only. Therefore it is recommended to check the performance
-yourself in order to decide whether to enable KleidiCV in a multicore
-environment.
