If you are being attacked at your planet and the game is going slowly, pause game play. Select what you want to buy and resume the game.
Faster production
There are two ways to build faster. The first is to build Robotic Factories, Morale Stations, and Robotic Workers. This way, more people will want to work. The other way is to speed up game time. Sometimes your selected governor (hero on the planet) may help to boost production and morale.
