say working simple class , object creation not heavy: class simple { public final int data1; public final float data2; ... } you have continuously put simple-objects queue: queue.add(new simple(123,123f,...)); is faster work object-pool , change simple-class modifiable class? hope not. generally, no isn't faster. if configure jvm use "throughput" gc, better performance not attempting recycle objects. worth considering object pools if either "memory constrained" or if gc pauses problematic. (the amortized cost of garbage collecting object tends towards 0 proportion of garbage non-garbage increases, if objects "die young", per generational hypothesis.) in fact: if application multi-threaded, object pool may concurrency bottleneck, and mutation of "effectively immutable" objects may require additional overhead and/or additional synchronization. if object creation rate "about 20 objects per second&quo
