It seems that Boost.MSM3-eUML2 (not sure what is the proper name?)
compiles
2.5 times slower than the eUML, but maybe there are some flags/options to speed it up?
Moreover, I'm not sure how to disable the slowing down options such as deffered events etc.? I would assume it should be as fast as eUML as it using the same back-end?
Compile-time is proportional to string length, reducing it would help. So would reducing BOOST_MPL_LIMIT_STRING_SIZE.
As they are empty, you can also remove you action definitions.
Cheers, I have been experimenting with BOOST_MPL_LIMIT_STRING_SIZE already. However, it would be a bit bias to remove actions/guards in order to speed it up as it would not reflect the real life example. I know they are not doing much in the example, but they still have to be called or removed by the compiler depending on the approach. For example msm-lite is affected by empty guards/actions if it comes to memory size as it stores them in order to call lambda expressions.
