+On my (few year old) laptop using AVX2 instruction set.  I'm not being very rigorous here.  The point is that it's really fast.

 ##### Leopard-RS *new*: O(K Log M) FFT MDS Reed-Solomon codec
 
-Encodes at 1.2 GB/s, and decodes at 480 MB/s for this case.
-12x faster than existing MDS approaches to encode, and almost 5x faster to decode.
+Encodes at 2 GB/s, and decodes at 600 MB/s for this case.
+20x faster than existing MDS approaches to encode, and 6x faster to decode.
 This uses a recent result from 2014 introducing a novel polynomial basis permitting FFT over fast Galois fields.
 This is an MDS Reed-Solomon similar to Jerasure, Zfec, ISA-L, etc, but much faster.
 It requires SSSE3 or newer Intel instruction sets for this speed.  Otherwise it runs much slower.
