Dear Mr. Sergio Garcia Thank you so much for your help. we are store Java objects in Memcached, I think it is difficute to reduce size of cached object because it depends on logic of the appliation. My I know which Memcached Java client are you using now? do you think we can solve it by improving source code in Memcached Java client?
