Version 8, Service Refresh 6, Fix Pack 31 (8.0.6.31)

New -XX:[+|-]AdaptiveGCThreading option

To optimize performance, you can now enable adaptive threading to automatically tune the number of active parallel garbage collection (GC) threads. When this feature is enabled, the GC thread count is dynamically adjusted from collection cycle to cycle to account for changes in the the amount of time that parallel threads spend doing useful GC work (such as object graph traversal) compared to time spent synchronizing among themselves. When GC parallel work (root processing, object graph traversal, etc.) decreases, fewer threads are used, which reduces the overhead, effectively reducing GC pause times. Resources are freed up for other processing activities.

Use the -xgcmaxthreads option with the -XX:+AdaptiveGCThreading option to specify a thread count limit.
