Can anyone suggest a robust algorithm for large systems treated with TD-DFT and with a diffuse basis set in Gaussian?

I'm currently trying to use Gaussian to obtain ECD spectra of a fairly large molecule in a mono- and dimeric state (roughly 150/300 atoms). I'm using TD-DFT with a DZV Dunning cc basis set, the...
