Description copied from class: GfxdServerLauncher

if heap-size is mentioned in the startup arguments and started within Sun JVM, following GC options are enabled by the script.

Parallel young generation collector (UseParNewGC) Concurrent low pause collector (UseConcMarkSweepGC) old generation threshold (CMSInitiatingOccupancyFraction) from default 68% to 50%.

On frequent full garbage collections with above options consider following GC options.

UseCMSInitiatingOccupancyOnly CMSFullGCsBeforeCompaction

For beyond 1 GB of physical memory and initial-heap/max-heap padding is enough consider additional options.

MaxNewSize=24m NewSize=24m CMSParallelRemarkEnabled

All JVM options can be passed from the command line using '-J' prefix.
e.g. -J-XX:MaxNewSize=24m

Overrides:

postProcessOptions in class GfxdServerLauncher

Parameters:

incomingVMArgs - vm argument list.

map - additional server arguments of command builder.
