准备工作

环境搭建（需要几台服务器几个节点）

数据准备

脚本编写、联调单次、多次数据校验，是否做了加密处理

场景设计业务和系统架构两方面分析选出实际生产环境可能会发生的场景

进行压测

关注点主要分为指标和日志

reponse time

HIts/sec

TPS

throughout/sec

-------------------------------------

cpu

mem

swap

net

jvm

GC情况主要关注FullGC 一般来讲 FullGc可以完全避免 10minute 发生1次fullgc 消耗1s 1minute发生一次 monitor gc 消耗10ms是可以容忍的
