When the database is fully loaded in the RAM, it will be much quicker.
Limiting the memory usage is always possible using the MySQL configuration file, in case RAM usage would be a problem, people can lower it or, Parallels could deliver the MySQL config with a low memory treshold, which users can increase based on their needs.
