### Question
- What do you want to know?
1、Why configured 1 number of consumer threads in org.apache.skywalking.apm.agent.core.remote.TraceSegmentServiceClient.boot()? can i largen this ？
（TraceSegmentServiceClient的boot方法第70行，carrier.consume(this, 1); 这个消费者的线程为什么配置的是1，有什么原因么？我可以修改变大这个参数么？）
2、In my agent log file（ skywalking.log） debug a lot of “DEBUG 2018-10-29 09:25:46 TraceSegmentServiceClient : One trace segment has been abandoned, cause by buffer is full. ”
How can i optimize configured （在其中一个项目忙时的时候agent的日志里有打印很多的trace segment 被丢弃，buffer满了，有没有可以优化的配置，防止数据丢失）
3、WARN More than 300 spans required to create ，can i configured 1000？（某些方法超过了300个spans，我可以配置到1000么？）
