title: Redis or Hazelcast, or others?
body: <p>I took an old web application recently. The App will save a lot of object into Ehcache at init time.And then obtain the object from the cache. And now, the object has increased many times. Ehcache in the app can not meet the requirement. So, we consider using a distributed cache. We will set some strategies and let the objects save in different cache server.
  Redis and Hazelcast are both good. Question is, the Redis and Hazelcast compared to the previous Ehcache, Redis and Hazelcast must <strong>Serialize</strong>  objects.  May be it will consume more time.
  So which is better? 
  Or are there no other better alternatives?</p>
  
  <p>Thanks in advance.</p>
