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?

Eric

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

But as for me and my household, we shall use Mozilla...
www.mozilla.org

Hmm, I means runtime performance, not the compile times :(

Using the profiler can help a lot!
