Edit: Post removed since the C library relies on SSE2. Will reopen and post once I got a cross-arch package available.
I want to perform some further tests with blake2b implementation in C.
This means that you need to compile the package for your platform.
I am more or less interested in the benchmarks on weaker devices (especially ARM’s and RPI’s).
This requires go and gcc
The instructions are as follows:
mkdir -p /tmp/src/github.com/AudriusButkevicius/blake2b-opt
cd /tmp/src/github.com/AudriusButkevicius/blake2b-opt
curl -L -O https://github.com/AudriusButkevicius/blake2b-opt/archive/master.tar.gz
tar -zxvf master.tar.gz --strip-components=1
./configure
cat /tmp/src/github.com/AudriusButkevicius/blake2b-opt/framework/include/asmopt.h > /tmp/benchmark.log
make install-lib util
go build blake2b.go
./bin/blake2b-util bench >> /tmp/benchmark.log
mkdir -p /tmp/src/github.com/AudriusButkevicius/gohashcompare
cd /tmp/src/github.com/AudriusButkevicius/gohashcompare
curl -L -O https://github.com/AudriusButkevicius/gohashcompare/archive/master.tar.gz
tar -zxvf master.tar.gz --strip-components=1
export GOPATH=/tmp
go build --ldflags '-extldflags "-static"' ./main.go
./main >> /tmp/benchmark.log
Afterwards, provide content of /tmp/benchmark.log here or ideally upload it to some pastebin.
Furthermore, you can help us by providing the following file:
/tmp/src/github.com/AudriusButkevicius/blake2b-opt/bin/blake2b.lib
by uploading it somewhere, but please also provide the name of your device.
Here the benchmark.log and blake2b.lib from my raspberry pi (model B 512MB) and my netbook (Intel Atom N450, 64bit but pretty slow)

@AudriusButkevicius What value is important? The MB/s?
Compare Hashing Performance.ods (19.4 KB)
We see that Blake2b is much faster than SHA256 on every platform.
I guess you can just do go run main.go to be honest.
Yes MB/s defines how fast we can crunch through the files.
