Comment(by nickie):
I was not aware of this, but it's not the issue here. The script I've
attached also measures user/system/elapsed time using /usr/bin/time and it
shows a clear difference:
{{{
Running with GHC 6.12.3
4.72 user 0.02 system 0:04.75 elapsed
Running with GHC 7.4.1
6.79 user 0.04 system 0:06.82 elapsed
}}}
