[Virtuoso-users] VOS 5.0.10 runs 'make check' 9.7% slower than 5.0.9 with identical CFLAGS/hardware

[Ceriel Jacobs]

Beside that parallel building is broken on VOS 5.0.10.
Another finding is that the 'make check' test runs 9.7% slower on VOS  
5.0.10 than it did on VOS 5.0.9:

5.0.9 : 2941 seconds
5.0.10: 3227 seconds

Environment:
Mac OS X 10.5.6
Xcode 3.1.2
Code2Duo processor

Build settings:
    CC=gcc-4.2
    CFLAGS="-fast -arch x86_64 -m64 -mmacosx-version-min=10.5 - 
march=nocona"

These non-default build settings provide about 63% faster (7849 vs  
2941 seconds) 'make check' than the your suggested default Mac OS  X  
10.5 64-bit flags:
    CFLAGS="-O -m64 -mmacosx-version-min=10.5"
