r3.8xlarge by Amazon Web Services


Bandwidth testing are conducted with local and block storages attached to the instance. We use the well-known open-source tool FIO. To express bandwidth the following parameters are used:

  • 1M block
  • Sequential access
  • No filesystem (except for write access with root volume)
  • Avoidance of cache and buffer
Specifications:
CPU
32
RAM
244.0 GB
