At QCon London, Holly Cummins emphasized the link between high performance software and sustainability. By improving algorithm efficiency, developers can significantly reduce energy consumption. Cummins advocated for practices such as turning off unused systems to minimize environmental impact. She highlighted how high performance systems should exhibit low memory usage, high throughput, and minimal networking, characteristics developers typically seek. Furthermore, she warned about the environmental costs of hardware production and e-waste, urging developers to identify and eliminate obsolete design assumptions in software to enhance efficiency and sustainability.
A high performance sustainable system should have a low memory footprint, high throughput, avoid excessive networking, and support elastic scaling.
E-waste can pose health hazards to the people doing the recycling, so the best way to solve the problem is to just generate less of it.
