Optimal Throughput GC policy
Optimal Throughput is a single generation Mark Sweep Compact (MSC) Stop-The-World collector. It is the default GC policy and is designed with speed in mind, so lengthy pauses during GC are to be expected.
Use Optimal Throughput when you want an application to run to completion as quickly as possible. This goal is usually at odds with typical WebSphere applications, but may be appropriate for very short-running applications.
Because Optimal Throughput is the default GC policy, no runtime option is required, although it can be set explicitly by entering...
-Xgcpolicy:optthruput
...in the Generic JVM arguments field in the JVM Process Definition page in the WAS administration console.
