We investigated how fork times influence performance on different AWS platforms and Redis dataset sizes. Fork is an expensive operation in Unix-like systems, causing delays in other operations. We tested Redis 2.4.17 on various platforms, including Xen-based instances, to find that fork time per GB of memory improves with stronger instances, but still causes significant latency. In contrast, the Redis Cloud minimizes fork times through several mechanisms and technologies, providing high performance at affordable infrastructure prices, even when dataset sizes grow.
