This page describes the hardware and software used when running the benchmarks.
Hardware
All machines used for benchmarking are provided by Amazon’s EC2 public cloud.
We use exclusively c5.2xlarge instances as described here.
The c5.2xlarge instance type has 8 vCPU (hardware threads) and 16 GiB of ram, with up to 10 Gbps networking.
Of particular note here, there are two generations of Intel hardware which may be used for any instance, entirely at Amazon’s discretion.
