If you have AutoOpenTables = .T. the tables get opened before the Load().

You don't tell us anything about the form. Do you load really large local views, or page frames with many controls, for example?

You can try using SET COVERAGE TO MyCoverage.TXT before you do your form, then SET COVERAGE TO in the init() of the form (at the end), then load the TXT file in the Tools | Coverage Profiler to see what code executes and how long it takes.
