Notes |
| k3d-gpu |
19.3 ms |
~30 sec |
Docker-native, fastest by far |
| Minikube |
35.8 ms |
~3-5 mins |
VM overhead, slower FS access |
| kind |
41.2 ms |
~2 mins |
Nested runtimes limit GPU use |
k3d-gpu provided the lowest latency and fastest provisioning time, making it ideal for ML experimentation.
