Laggy performance with large data sets

Slow loading in itself would not be much of a problem, but following it, running many operations such as appending a wave to a graph, opening the Curve Fit panel window, or performing the fit itself, are accompanied by a pause that lasts a few seconds.
This issue is not the system I'm using (17-inch MacBook Pro 2011, with 16GB RAM, 2.5GHz Quad Core i7, 512GB SSD with ~100GB free, running OS X 10.8.4), since other applications run very fast even when Igor is crunching its numbers on these experiment files. Igor is also using only about 500MB RAM, which is significantly lower than what I'd expect it could use, given that 32-bit applications have a ~4GB limit.
Is there some way to increase Igor's memory allocation if this is a contributing factor, or otherwise make loading and using large data sets faster?
