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
IO
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
