Benchmark for SHA-3 (Shake128) I am trying to find the average of hash rate (benchmark) for SHA-3(Shake128) for a normal and supercomputer in order to estimate the brute-force attack which I can get if from ( keyspace / hash rate )...then I found this website:

https://bench.cr.yp.to/results-hash.html 

I could not understand these tables i.g. (Cycles/byte for 8 bytes) what do they mean by cycles/byte? Is it that hash rate for 8-bytes?
Cycles per byte means the number of CPU cycles that must elapse in order to process a single byte of input for a specific processor. A CPU's clock frequency determines how many cycles per second the processor is running at (for example, 2.6 billion per second for a 2.6 GHz processor). Note that this is a rather crude type of benchmark, because the bottleneck may not be waiting for each instruction to retire. Memory access latency, shared resources, etc. can slow things down.
