Doing dev work in docker on a mac may be workable!

| | Rails Boot | Slowdown |
| --- | --- | --- |
| Host | 5.64 | |
| Virtual Box | 6.15 | 9% |
| Virtual Box + Docker | 8.78 | 55% |
| Docker Mac (cached) | 11.2 | 98% |
| Docker Mac (uncached) | 15.7 | 178% |

**Note** : for Docker setup on virtual box has gems are in AUFS and working directory in a mounted volume. On mac the working directory is a cache mounted volume. It is likely performance would improve if overlay was used or gems are mounted on the host to avoid virtualized file system.

### Docker for Mac … uncached:

```plaintext
sams-MBP:discourse sam$ time d/rails r 'puts'

real	0m19.035s
user	0m0.016s
sys	0m0.014s
sams-MBP:discourse sam$ time d/rails r 'puts'

real	0m15.702s
user	0m0.017s
sys	0m0.014s
sams-MBP:discourse sam$ time d/rails r 'puts'

real	0m17.290s
user	0m0.016s
sys	0m0.011s

```

### Docker for mac .. cached

```plaintext
sams-MBP:discourse sam$ time d/rails r 'puts'

real	0m11.430s
user	0m0.018s

```

### Ruby installed on host

```plaintext
sams-MBP:discourse sam$ time bin/rails r 'puts'

real	0m7.204s
user	0m4.541s
sys	0m1.780s
sams-MBP:discourse sam$ time bin/rails r 'puts'

sams-MBP:discourse sam$ time bin/rails r 'puts'

real	0m5.646s
user	0m4.329s
sys	0m1.256s

```

### VirtualBox + docker on the same host

```plaintext
sam@ubuntu:~/Source/discourse$ time d/rails r 'puts'

real	0m12.519s
user	0m0.016s
sys	0m0.012s
sam@ubuntu:~/Source/discourse$ time d/rails r 'puts'

sam@ubuntu:~/Source/discourse$ time d/rails r 'puts'

real	0m8.733s
user	0m0.008s

```

### VirtualBox, no docker

```plaintext
