c++ - Performance compare to VC8?

- Jan Knepper (8/25) Dec 20 2006 Turn off optimization, -o+all, that could be a killer for short compile

Hi,
I try use dmc compile AGG(www.antigrain.com) examples, and
compare to VC 2005 Express Edition, for VC, I use /O2 /Ob1,
and dmc options i: -o+all -ff
Here is the result for examples\gradient_focal:
speed size
VC8 30 ms 192 kb
DMC 43 ms 139 kb
My CPU P4-2.4G, is there any compile options to improve the performance?

Turn off optimization, -o+all, that could be a killer for short compile
times...
