f1cbffdd3e 6819077: G1: first GC thread coming late into the GC
The first worker thread is delayed when entering the GC because it clears the card count table that is used in identifying hot cards. Replace the card count table with a dynamically sized evicting hash table that includes an epoch based counter.

The size of the chunks that each thread will claim is determined at VM initialization from the size of the card cache and the number of worker threads.
