Marshini Chetty presented our paper “Measuring Broadband Performance in South Africa” to the 4th ACM Symposium on Computing for Development (DEV). The paper includes several new and important findings, including:
- Fixed and mobile throughput does not achieve the rates advertised by ISPs (in contrast to countries such as the US, where performance more closely matches advertised rates).
- Mobile throughput is consistently higher than fixed-line (e.g., DSL) throughput, although both throughput and latency are considerable more variable on mobile providers.
- Latency to other destinations on the African continent can be quite high, due to Internet routes that “detour” through Internet exchange points (IXPs) in Europe (e.g., Amsterdam Internet exchange, London Internet exchange).
