What should I do to reduce Materials Studio lag?

I am constructing a massive polyhedral supermolecule containing around 10,000 atoms, but as number of molecules grow, the software lags more severely, to the extent where every edit I make (including making bonds and selecting atoms), results in a 10-second lag, along with a short period of "Software Not Responding". How do I fix this? I tried allocating more RAM to the software by changing the priority of the software via Control Panel, but it did not work. Is there any solution to this problem? Thank you very much.
