Hazelcast vs Redis

Overview

Hazelcast has performed a number of performance benchmarks against Redis providing a core set of conclusions:

  • Hazelcast consistently outperforms Redis at scale. Hazelcast is faster than Redis at scale and the gap widens as the workload increases. The benchmarks show that as the workload increases (thus requiring more concurrent threads), Hazelcast maintains its high-throughput and low-latency performance.
  • Published benchmarks that favor Redis do not use equal comparisons. In our latest benchmark reports, we call out several discrepancies in other benchmarks (not run by Hazelcast) that skew results in favor of Redis. Once the tests and configurations are normalized, Hazelcast performance outshines Redis.
  • The Hazelcast architecture is the key to performance. Hazelcast was built for performance; for example, its multi-threaded architecture (Redis is single-threaded), near-cache, pipelining, and other capabilities give customers the highest throughput and lowest latency.
