[infinispan-dev] Memory consumption of ISPN 5.3 in compatibility mode

[Divya Mehra]

Indeed, very encouraging!

Would be great to compare performance of the compatibility mode.

Thanks,
Divya

Very nice the fact that memory consumption out-of-compatibility mode has improved significantly in 5.3.
Also in the case of HotRod, even in compatibility mode, the memory consumption is the same as in JDG 6.1.
