Local vs. Cloud VM

Local vs. Cloud VM

Evaluate the performance discrepancy between a locally attached block storage device and network-attached object storage from the perspective of an isolated virtual machine.

Use fio to evaluate the read/write performance discrepancy between a locally attached block storage device and network-attached block storage on a virtual machine.

Check the discrepancy between volatile temporal storage (typically /tmp/) and non-volatile temporal storage (typically /var/tmp/).

• Use df to check the type of temporal storage.

• Use fio to perform a read/write profiling.

fio overwrites!

HPC Cluster (Shared Filesystem)

Avoid performing benchmark tests

Benchmarking a shared filesystem is almost never a good idea! You will be a very noisy neighbour!
