$('#ObjectMaster #FirstName') should give you almost the exact same
performance of $('#ObjectMaster').find('#FirstName'), as the exact
same is happening internally. There is the option of using a context:
$('#FirstName', ObjectMaster)
but I'm not sure that would give you any performance increase.
Most important, as Mike has pointed out, IDs are meant to be unique.
You'll certainly run into other problems this way, use classes
instead.
