Tuning Serial and Parallel Collectors in SPECjvm2008

Many object-oriented programming languages like Java and C# are gaining importance in the development of reliable and robust applications because of the presence of Garbage Collectors. There are multiple Garbage Collectors (GC) available in JDK 1.7.0_04. In the current research we compared the performance of serial and parallel collectors with respect to SPECjvm2008. It has been found that the behavior of the Garbage Collector is application specific. Not all the benchmarks require same size of heap for its invocation. There is considerable amount of difference in heap size for initialization of Garbage Collector. The value of optimal size of the heap varies from 100 megabyte (mb) to 400 mb for different benchmarks. In the current research, benchmarks available in SPECjvm2008 are considered over a wide range of Heap size.
