scripts to quickly measure system baseline IO performance
This is meant to be a quick way to get some comparable performance numbers from a system. The goal is to be able to clone the repo and do minimal configuration before getting results. As well, the set of tests will be chosen to be useful for a round assessment of systems, but simple enough to allow for side-by-side comparison with results from different systems.
- fio (could be in the Linux repository as well)
bin/run-fio-tests [-c config_dir] [-j] -r results_dir -d data_dir [number_cycles]
Parameters are:
-r(required) - full path to directory where results will be stored;-d(required) - full path to directory where tests will be executed;-c(optional) - path to directory with configuration files (./conf/by default);-j(optional) - output data in the JSON format instead of human-readable.
The full test battery will run 53 full-speed microbenchmarks, with IO workloads simulating various levels of streaming reads, writes, random reads, and combinations of these.
Each test is also coded with a test id, to make cross-comparisons and discussion easier.
If you want to run an partial set of tests, you can use the syntax
bin/run-fio-tests -r results_dir -d data_dir 10
This will run the most basic tests first, filling in gaps in the results as the tests continue. Details on the test order are in test_order.lst
