Benchmark

Tart comes with a Golang-based benchmarking utility that allows one to easily compare host and guest performance.

Currently, only Flexible I/O tester workloads are supported. To run them, install Golang and run the following command from this (benchmark/) directory:

go run cmd/main.go fio

You can also enable the debugging output to diagnose issues:

go run cmd/main.go fio --debug

Results

Host:

  • Hardware: Mac mini (Apple M2 Pro, 8 performance and 4 efficiency cores, 32 GB RAM, Mac14,12)
  • OS: macOS Sonoma 14.4.1
