Subra:

If the POJO has no synchronized blocks inside it, there is no reason for performance to be hit. Theoretically, and concretely, the two following systems will perform almost equivalently, with system A performing slightly better than system B.

System A: Single POJO singleton, with 1000 clients accessing it.
System B: 1000 POJO instances of same class, with 1000 clients accessing the instances.
