(In reply to Basile-z from comment #9)
> How worth is this to fix considering that there are plan to deactivate -release for the official build ?

Building without -release is different from building without optimizations. Enabling asserts will probably cost a couple of percent, not 30-40%.

--- Comment #12 from GoaLitiuM <goalitium@dissues.mail.kapsi.fi> ---
Here are the latest measurements when building a project including few dependencies with DUB (results are not comparable to my previous post):

2.089.0 built with LDC2
time elapsed: 8.2s

2.089.0
time elapsed: 15.3s

2.090.0
time elapsed: 15.3s

2.090.1-beta
time elapsed: 11.0s

The beta release clearly helped with the performance, but there are still room for improvements. You really should consider using LDC2 for final builds which seems to produce way more optimized binaries than DMD.
