Redis vs Memcached for object cache

Redis vs Memcached for object cache
Memcached is a dumb fast key blob store — multithreaded, scales across cores, zero features. Redis is single-threaded but does persistence, data types, and pub/sub.
— Pure page/object cache, multi-core box, want raw throughput: Memcached
— Sessions you can't lose, queues, rate limiters: Redis
For WP object cache on one core, honestly either flies. I keep Redis because I reuse it for queues. Don't run both for one site. Try it tonight.
