(2)hash算法分片，虚拟节点是什么意思？

https://www.sofastack.tech/blog/sofa-registry-introduction/

（3）data的性能：

跟什么有关呢？什么存储原理呐？

（4）断连指的那里？

是否断连是指的吗？

没有断连，但data挂了，是无法感知的？

8.查看性能用到的Linux命令：

（1）ps -aux --sort -pmem  #-aux 按照CPU或者内存用量来筛选进程（http://noahsnail.com/2017/02/21/2017-02-21-Linux%E7%9A%84ps%E5%91%BD%E4%BB%A4/）

输出格式：USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

（2）ps -auxf | sort -nr -k 4 | head -10  #找出占用内存最多的前十个进程；

（3）修改JAVA进程的CPU和内存使用大小，通过执行java -Xmx4096m  ................等命令即可;
