Hibernate-memcached set every key again on request

[bas moorkens]

Hi,

I am using hibernate-memcached in an application, and on startup it loads a large quantity of objects into the memcached server.
Whenever I make the application do a request after this, it tries to find the key in memcached, but it doesnt. So it sets the key again.

This is just a test I am performing to replace the 2nd level cache from hibernate from EhCache to MemCached.
The problem is it is a lot slower then when I used Ehcache. Is this a normal effect or do I have made a configuration error somewhere?
 
My memcached is configured in following way:

hibernate.cache.use_second_level_cache=true
hibernate.cache.use_minimal_puts=true
hibernate.cache.provider_class=com.googlecode.hibernate.memcached.MemcachedCacheProvider
hibernate.memcached.servers= testvm:11211
hibernate.memcached.cacheTimeSeconds=720

Sample output from my memcached server instance typicly goes like this:
