Bug#855359: darktable: 2.2.1 binary very slow compared to self-compiled

[Matthias Bodenbinder]

Package: darktable
Version: 2.2.1-2
Severity: normal

The darktable binary from debian testing is very slow compared to a 
self-compiled version. 
1) apt-get install darktable
The darktable-cli benchmark I am using takes 22 seconds to complete

2) apt-get source darktable && compile myself
The darktable-cli benchmark takes only 15 seconds

I repeated the test several times.

Major performance difference.
My hardware: core i7-7700k with MSI.Z270 GAMING PRO CARBON (MS-7A63)
