- As fast as java.util.HashTable for single threads
- As fast as ConcurrentHashMap for < 32 cpus and >95% read rates
- Faster for higher write rates than ConcurrentHashMap. (2x to 8x faster, depending)
- Faster for more CPUs. Much faster if not striping ConcurrentHashMap enough (easily 100x faster)
- Scales linearly for all read/write rates at least up 750 cpus. Tested on 4-way X86, Niagra, 32-way UltraSparc2, 384-way Azul Vega1 and a 768-way Azul Vega2.
