Prevent large gclog file for long running app. Number of gclog files in rotation. GC log file size, Default: 0 bytes, no rotation. Bump the number of file descriptors to max in solaris.
Run user-defined commands on first java. Register finalizable objects at end of Object. Where possible replaces call to Integer. Use parallel garbage collection for scavenges. Use parallel garbage collection for the full collections. See good explanation about that parameter here. Enables object-reference compression capabilities via the Compressed References.
Have sense just on 64bit JVM. Use parallel threads in the new generation. Retain parallel allocation buffers across scavenges. Number of blocks to attempt to claim when refilling CMS LAB for parallel GC. It forces all freshly committed pages to be pre-touched. The multiple of deviation from mean to use for buffering” against volatility in free list demand. The multiple of deviation from mean to use for buffering” against volatility in inter-sweep duration.
See good explanation about that parameter here. Only use occupancy as a crierion for starting a CMS collection. The youngest generation collection does not require” a guarantee of full promotion of all live objects. Print the time taken by each parallel old gc phase. Enable aggressive optimizations – see arguments.
