Hello,

I've made some experiments with build options (project properties of ocx). Here are results:

Size of ocx:
repository version 9.17 MB
mine 7.53 MB

speed of opening edit mode (15MB poly shapefile)
repository version ~11sec;
my version ~7sec;

My version has no differences in code (only additional methods/properties - I'll commit them soon).
It seems that differences in speed affect all functions which deal with COM classes like CShape, CExtents. The problem - I'm not sure which options have effect on speed.

Options I changed (exactly):
Linker\General Enable Incremental linking YES->NO (size depends on this option)
C/C++\Optimization Optimization Disabled->Full Optimization
C/C++\Code Generation Enable C++ Exceptions Yes(/EHsc)->No (it's not acceptable for release build I expect)

There are other differences with current SVN version (in SVN diff) but I don't know whether they are significant or not. I have updated versions of support libraries and haven't deleted any dependencies.

It seems we should review options used for release builds.

Regards,
Sergei

Sergei,

In the new Release RC3 your suggestions will be used, except the C++ Exceptions.

RC3 will hopefully be released later today.
