Yes, the mapper creation is very time consuming, especially compared to the time spent using the generated mapper. But as the mappers are cached during production, the app only needs to render them once, when the app is deployed.
This gives a huge performance increase, as only the connection, query builders, mappers and data objects needs to be loaded. So instead of loading 50! files, it only loads about 7 + 1 for each mapper.
To activate the mapper cache, set $cache_mappers to true (the variable is located in app/config/database.php).
To refresh the mapper cache, just delete all the files which are located in app/mappercache and RapidDataMapper will refresh them automatically.
