The Reference Architectures were built and tested with the Intel Xeon E5 v3 (Haswell) CPU platform on GCP.

Below is a Sysbench benchmark of the CPU from a n1-highcpu-32 instance for comparision:

sysbench 1.0.19 (using bundled LuaJIT 2.1.0-beta2)

Running the test with following options:
Number of threads: 32
Initializing random number generator from current time


Prime numbers limit: 20000

Initializing worker threads...
