The benchmark described for Intel Xeon is run with a Highbank ARMv7 Processor rev 0 (v7l) processor (the maker of the processor was Calxeda ), using the same codebase:
The encoding speed is ~450MB/s for K=2,M=1 (i.e. a RAID5 equivalent) and ~25MB/s for K=10,M=4.
It is also run with Highbank ARMv7 Processor rev 2 (v7l) (note the 2):
The encoding speed is ~650MB/s for K=2,M=1 (i.e. a RAID5 equivalent) and ~75MB/s for K=10,M=4.
Note: The code of the erasure code plugin does not contain any NEON optimizations.
