I update dmd+phobos two or three times a year. Recent update changed my project compilation time from 11 sec to 18 sec (+64%).
I'm not sure, but previous update probably changed it from 8 sec to 11 sec which was still acceptable. Looks like we finally have twice slower compilation time than year ago and still slowing down. Not sure is it a compiler or Phobos changes.
IMO we should either fix compilation time (I have no idea how be the way) or inform D users compilation time constantly increases so they can account it deciding to update or stay with an old version.

Please, comment here your own experience. In the best case it's just something wrong with my configuration and this is invalid.

Unfortunately this issue is not actionable.
Tracking compilation performance is something we want to do in general, but it is a very broad subject.
Tracking a regression in build time of a specific project may be more directly actionable (or at least possible to investigate), but no test case has been provided.
I'll close this as it was filed 3 years ago, and there doesn't seem to be much utility in leaving this open today.

What about "Is D slim yet?" http://digger.k3.1azy.net/trend/ produces an error for me:
An error occured while loading the graph data (data/data.json)
parsererror: SyntaxError: Unexpected end of JSON input

Yep, that was my effort on improving the situation with regards to the general problem.
That project has been superseded by a CI system which integrated it, however I abandoned work on the CI system after being told custom CI systems are a bad idea.

BTW, that error manifests because the amount of data has grown so large that browsers now choke on it. I need to seriously refactor the front end to make it stream in data as needed from the server instead of loading it all at once.
