In your dub.json, can you use the following:

     "subConfigurations": {
         "vibe-d": "libasync"
     },
     "dependencies": {
         "vibe-d": "~>0.7.24-beta.3"
     },


Turns out it makes it much faster on my machine (371ms vs 
1474ms). I guess it could be a good thing to investigate if we 
can make it the default in 0.7.25.
