Improve performance of DataSet.InitClass

I inherited a giant dataset that my profiler notes that the InitClass method takes over 5 seconds to load.

This is generated code so, other than removing unneeded datatables etc... is there anything I can do to improve the performance of this method?

This is in VB.NET

EDIT

The profiler says that 99% of the time is spent inside the method it开发者_Go百科self, I looked at this method and it adds 14 tables and their relationships.

I'm using the EQATEC free profiler (version 3.0.46) and it's not telling me which line is taking the longest, only that the there are 30 method calls in the InitClass method and they take <1% of the time spent.
