Galder Zamarreño commented on ISPN-868:
---------------------------------------

Btw, if you're comparing Infinispan and EhCache, I don't think the memory settings for the different caches in EhCache match the ones for Infinispan:

[2011-01-13 11:01:28.437,     0]WARN [main](Cache.java:950) - Cache: kiwi has a maxElementsInMemory of 0.  In Ehcache 2.0 this has been changed to mean a store with no capacity limit. Set it to 1 if you want no elements cached in memory
[2011-01-13 11:01:28.481,    44]WARN [main](Cache.java:950) - Cache: carton has a maxElementsInMemory of 0.  In Ehcache 2.0 this has been changed to mean a store with no capacity limit. Set it to 1 if you want no elements cached in memory
[2011-01-13 11:01:28.482,    45]WARN [main](Cache.java:950) - Cache: container has a maxElementsInMemory of 0.  In Ehcache 2.0 this has been changed to mean a store with no capacity limit. Set it to 1 if you want no elements cached in memory
[2011-01-13 11:01:28.484,    47]WARN [main](Cache.java:950) - Cache: pastry has a maxElementsInMemory of 0.  In Ehcache 2.0 this has been changed to mean a store with no capacity limit. Set it to 1 if you want no elements cached in memory
[2011-01-13 11:01:28.504,    67]WARN [main](Cache.java:950) - Cache: egg has a maxElementsInMemory of 0.  In Ehcache 2.0 this has been changed to mean a store with no capacity limit. Set it to 1 if you want no elements cached in memory

So, if you were to compare them equally, I suppose you'd have to change maxElementsInMemory to 1000 for all caches in the ehcache config too?

> While running a load test data builder for our application we ran out of memory very quickly.  A simple test case (attached) was created to duplicate the issue.  We found running the simple test case illustrates that Infinispan uses a large amount of heap space.
> As a reference the same test was run using EHCache 2.2.  Memory usage was much lower; we never ran out of heap space.  Note that EHCache was used as a reference only, our goal is to go to production with Infinispan.
