The garbage collection bottleneck

Examining Java garbage collection can give insight into how the application is utilizing memory. Garbage collection is a Java strength. By taking the burden of memory management away from the application writer, Java applications are more robust than applications written in languages that do not provide garbage collection. This robustness applies as long as the application is not abusing objects. Garbage collection normally consumes anywhere from 5 to 20% of the total execution time of a properly functioning application. If not managed, garbage collection can be one of the biggest bottlenecks for an application, especially when running on SMP server machines.
