I would be interesting to have the /same/ application compiled withj the old
SMTp version and compiled with the new SMTP version. Then run both
applications on the same computer using the same datas and the same server.
This way we can be sure that everything else is identical and only the
component is different.
When compiling applications, be sure to use the same options (for
optimization and others) and use the same tools (I think about MadExcept,
MemorySleuth, FastMM and other tools.
When using V6, search for all OutputDebugString which are into the
component. They may slow down execution somewhat, specially if you use a
tool to see those messages, event the IDE. There are also option to compile
or not logging informations. Again this slow down the operation.
