关于tomcat并发的问题。? 400 报错

这个100%是应用程序的问题啦
######经过统计，每个页面的响应时间还没有超过20ms呀。######什么错，jvm什么参数。######JAVA_OPTS='-Xms512m-Xmx512m'######哎呀，头疼呀。现在也不知道问题出在哪里了。

######报的错误是form中的值丢了。在页面中取不到。######最好贴出错误......应该是你应用的问题,和容器没有关系######换resin试试######贴log######100个并发还是小意思的。
######谢谢大家，找到问题点了。

现在我才用了两种压力测试。结果差距比较大。大家看看那个比较合适的。
