-----------------------------------------------------------
We had make a test to compare two way performance,it seems use custom EventBus
has more better performance:
| |custom EventBus|guava EventBus|
|tps|1,000,000 +|500,000 +|
|latency|1ms|1.8ms|
|consumer cpu|about 650%|about 500%|
|producer cpu|about 750%|about 800%|
May cause by guava EventBus invoke subscribe method via java reflection
mechanism,need more deep code analysis later
*So we do not apply this Jira current*
Detail:
