The lesson here—and in general for object reuse—is that when initialization of objects takes a long time, don’t be afraid to explore object pooling or thread-local variables to reuse those expensive-to-create objects. As always, though, strike a balance: large object pools of generic classes will most certainly lead to more performance issues than they solve. Leave these techniques to classes that are expensive to initialize, and when the number of the reused objects will be small.
