If you have an item with key K in the cache already, then an ADD operation on K will fail because it's already there. (an add operation only succeeds when that key does not already exist). A set operation will always succeed overwriting the existing value if any.
The speed of both should be the same. -- Jehiah On 7/31/07, Hanson Char <[EMAIL PROTECTED]> wrote: > If an item with key K already exists in memcached, would an add > operation of the same key K be faster than a set operation in general > ? > > Hanson >
