FIO performance benchmarks

FIO is an industry standard benchmark for measuring disk IOPs (Input Output operations Per Second). We include it here as a baseline measurement on all infrastructure to compare raw disk performance that any application can potentially achieve. Note that this IOPs is not necessarily a measurement for high volume throughput application, a disk bandwidth tool such as dd or vdbench provides a more suitable measurement for this.

Raw data

The same fio config file is used in all cases and can be retrieved from here. Make sure to change the config file to access the correct block device name that you wish to test, e.g. /dev/sda or /dev/xvda or /dev/nvme0n1

Flavour Read IOPs Write IOPs
AWS r5.2xlarge + 50K reserved iops 18.7
SUnlight AWS r5.2xlarge 428
Sunlight r5.2xlarge 651
