Because MySQL is basically a file-system and not a true database, it is faster
Like MySQL and PostGres it's free. Except Oracle XE is crippled in that it will only allow databases up to 4GB, will only use 1GB of RAM, and will only use 1 processor (if you have more than one). If your application fits within those limits then it *might* be faster than MySQL, but probably only if you're using it in a transactional sense. MySQK with MyISAM tables should be very, very fast. Especially if you have a machine with specs that exceed the limitations placed on Oracle XE
