The [performance](https://github.com/ben-manes/caffeine/wiki/Benchmarks) should be relatively the same and the per-instance memory usage should be smaller.\r\n\r\n[ConcurrentLinkedHashMap](https://code.google.com/p/concurrentlinkedhashmap/) changes will continue to be minimal, even more so now, and driven by requests from Java 6 users unable to upgrade. Caffeine is ideally the upgrade path for Guava cache users too, which due to Android cannot be significantly modified."}}
