I've finally taken the time to do the first step and integrated a simple 
benchmark target into a fork of the benchmark suite:

https://github.com/s-ludwig/FrameworkBenchmarks/tree/master/vibe.d

It's still very rough and misses the actual DB queries and proper 
testing of the setup scripts. If anyone with a running MySQL server and 
some experience with the mysql-native driver wants to add the missing 
query execution code that would be great!

The most obvious possibility for improvement is the JSON serialization. 
That currently allocates twice, once for T->JSON and once for 
JSON->string -- it shouldn't allocate at all. Since std.serialization 
still seems to take some time, I'll probably add something to the 
existing serialization code in vibe.d for that.
