Vitalik posted an article urging ZK and FHE developers to measure efficiency loss by "performance ratio".

Odaily News Ethereum founder Vitalik Buterin stated that he hopes more zk-SNARKs and fully homomorphic encryption (FHE) developers can present performance overhead as the “ratio of encrypted computation time to raw computation time,” rather than just describing performance in terms of “executions per second.” He pointed out that this method is more hardware-independent and can help developers assess the efficiency trade-offs when transitioning applications from “trust reliance” to “encryption security.” Vitalik believes that even though operational heterogeneity still affects the ratio based on hardware, the overhead factor remains a more informative metric.
