Medium-3 by CloudSigma
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
