Which compiler did you use for D?
I've used newest LDC.
In benchmarks where some fixed amount of work should be done as fast as possible low CPU usage is not a good sign, it just means some cores were idle when they could really be working.
Not in this case, there is a batch of the job that need to be done parallel but second part is done sequential (that takes majority of the time) so in this case this is good. Just look at source code of the algorithm in the link I've provided. I've also looked at callgrind and majority of the time is spent in regex so it's good.
