Getting the collection of checkboxes

Hi,
  I have a form wherein there are around 200-300 rows of homogenous
data, each having around 30 input fileds of its own.So totally, there
are more than 6000 input fields . Now, when the user submits this page,
i need to loop through the checkboxes and identify the ones that are
checked. I can't use the getElementsByName() since the checkbox names
are different. I'm using getElementsByTagName("input"). Because of the
huge amount of data, this method takes around 4-5 secs to evaluate
before submitting the form. Is there some way to get the collection of
checkboxes without having to loop through all the input fields?
