* Get a fresh instance of executor for each benchmark invocation And don't pre-initialize all of the executors at once, as this might reach the maximum number of VMs limit in case we want to test multiple Tart executors. * Run benchmarks on Tart with different --root-disk-opts options * Fix TestTart * benchmark fio: introduce --prepare command-line argument To be able to specify --prepare='sudo purge && sync', similarly to Hyperfine[1]. [1]: https://github.com/sharkdp/hyperfine * Benchmark Tart with --root-disk-opts=caching=cached separately too * Add Ars Technica recommended benchmarks * Tart executor: log SSH session standard output and standard error * Reduce file I/O size from 16 to 10 GB to avoid "No space left on device" * Remove random writing tests to make space for more read/read-write tests * Add some "randrw"-style fio benchmarks * Show latency in benchmark results * Add sync benchmark and show read/write/sync latency * README.md: add new benchmark results
