W3 Total Cache page caching with memcached – low memcached hit rate
I’m running W3 Total Cache on two WP servers backed by a DB server running MySQL and Memcached. The page caching is using Memcached, which is configured with:
MAXCONN=1024 CACHESIZE=512 OPTIONS=""
I’m watching memcache-top and seeing only 64% hit rate on memcached (usage is 1.6% so there’s plenty of space I think). The server running memcached seems very lightly loaded, load avg 0.01, CPU practically 0%, approx 30% of the RAM free.
Are there some Memcached options I can tweak to improve the hit rate?
Thanks in advance for any suggestions.
