Current implementation of Groestl is quite slow (<1 MB/s) and can be significantly improved. Various performance improvement techniques can be found in the "[Grøstl Implementation Guide](http://www.groestl.info/groestl-implementation-guide.pdf)". List of the fastest implementations can be found [here](http://www.groestl.info/implementations.html).
