 This algorithm reports its own load information to the registry at regular intervals. Make decision on two main pieces of information:
 
 - load average (default is the number of CPU cores * 2)
-- available physical memory (default is 0.3, in G)
+- available physical memory (default is 70%, in percentage)
 
 If either of these is lower than the configured item, then this worker will not participate in the load. (no traffic will be allocated)
 
-You can customise the configuration by changing the following properties in worker.properties
-
-- worker.max.cpu.load.avg=-1 (worker max cpu load avg, only higher than the system cpu load average, worker server can be dispatched tasks. default value -1: the number of cpu cores * 2)
-- worker.reserved.memory=0.3 (worker reserved memory, only lower than system available memory, worker server can be dispatched tasks. default value 0.3, the unit is percentage)

 该算法每隔一段时间会向注册中心上报自己的负载信息。我们主要根据两个信息来进行判断

 如果两者任何一个低于配置项，那么这台 worker 将不参与负载。（即不分配流量）
