Huge variations for test-refs running time
Running test-refs on different environments shows huge differences for the time required to perform the test.
Windows 7 (virtualbox guest on linux host - 4 cores)
Start 14: test-refs
14/25 Test #14: test-refs ........................ Passed 220.80 sec
Windows 10 (virtualbox guest on linux host - 1 core)
Start 14: test-refs
14/25 Test #14: test-refs ........................ Passed 10.00 sec
Wine (16 core linux system, host for above mentioned guest systems)
Start 14: test-refs
14/25 Test #14: test-refs ........................ Passed 86.65 sec
The huge time for running with wine is a known issue. I was fixed with bug https://bugs.freedesktop.org/show_bug.cgi?id=92538 and worked 3 years ago, but unfortunally not with current wine versions (3.x)
