VM.Standard.E4.Flex.8-32 by Oracle Cloud

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

RAM

32.0 GB

Net

8000 Mbps

800GB Paravirtualized block volume
