I've instructed memcache to append stats to each page. Someone did an excellent job explaining the memcache reporting page. However, I've since stumbled upon this appended information shown below and am curious.

Specifically what are miss and hit status?

The hit/miss statuses are the result of the cache being touched as the result of the operation. For the given operations:

  • Get: (for a single key) Hit: data was retrieved from the cache; Miss: data was found not in the cache.
  • Set: Hit: data was stored in the cache; Miss: data was not stored in the cache.
  • GetMulti: (for multiple keys) Hit: data was retrieved in the cache; Miss: data was found not in the cache.
  • Delete: Hit: data was removed from the cache; Miss: data was not removed (for a missing key) in the cache.

  • So hits > miss is good.

  • For gets, yes, you want the hit/miss ratio to be as high as possible.
