For me the new v8/9 is faster. 13min against 17-18. (Intel compiler SSE41)

Several of my machines (running OS X) are taking about twice as long to complete a unit as they did before. I don't know if it is due to the new types of units or the new application. Is there a new adjustment to the credit award in the works?

(addendum to previous message):
The problem appears to be on the Intel powered Macs; the PPC Macs are running about the same as before.

I changed some of the compiler flags which supposedly would make it run faster. Seems like they haven't so I'm going to update the app again which should fix the problem.

I was trying some of the ones suggested in the code forum. I just went back to the old flags, so v0.10 is using:

osx, x86_64:
-O3 -mfpmath=sse -mtune=nocona -msse3 -ftree-vectorize -funroll-loops

osx, i686:
-O2 -msse2 -mfpmath=sse -mtune=prescott -ftree-vectorize -funroll-loops

osx, ppc:
-O2 -maltivec -mabi=altivec -mcpu=7400 -funroll-loops

linux, x86_64:
-O2 -msse2 -ftree-vectorize -pedantic -funroll-loops

linux, i686:
-m32 -O2 -ftree-vectorize -pedantic -funroll-loops


I'm not sure what compiler flags Dave is using for the windows versions.

Yeah, the OS X flags look fine to me (where I specialize ;-) ).

Please use -march=nocona instead of -mtune=nocona.
-mtune will tune the code for specific processor, but -march will actually use the processor specific instructions (and implicitly set -mtune for the target architecture)
