Using Redis as the backend for Magento cache and Magento sessions (through Cm_Cache_Backend_Redis and Cm_RedisSession with phpredis), what is the best performance wise with respect to the "persistent" section in local.xml?
The example configs Colin gives show no unique value for persistent. The comments say there may be bugs. The Tuning section says to enable persistent connections.
What are the pros/cons to enabling persistent connections with Redis and Magento for caching and sessions? Thanks for any details.
