no... the settler time stays the same unless you use a love potion
mayor house has nothing to do with settler spawn rate or max number of settlers, upgradeing mayor house just gives you more storeage space to store your resorces etc.
Building or upgradeing residences will increase your settlers max population.
Indeed, Search the forum and you will find tips and tricks what mayor house is and what it can do. Good Luck
Bear in mind, it takes less resources to upgrade your store houses.
