LoadRunner响应时间在某个点突然很大

hbpad 发表于 2009-6-7 11:49:30

设置了150个用户,在运行了一个多小时后看结果,发现在120个用户的时候响应时间突然很大,之后又正常了,请问这样一般是什么原因造成的啊?是不是系统能容纳的并发最大用户数就是120个了呢?

120个用户的时候响应时间忽然很大，之后又正常了，这个？你能不能把你的场景策略也说说呢

不能发图片~ 设置了150个用户,每隔20秒启动5个用户,停止的时候是每隔30秒停止5个用户,持续运行时间是1个小时,总共运行了1个小时25分17秒,看它的响应时间,是在35分钟左右的时候有个高峰,虚拟用户为120的时候有个最高峰,其他的都比较平稳

yzylion 发表于 2009-6-7 14:30:10

这样啊？那按这样的话，8分钟的时候就应该有120个用户在跑了啊，你在120个vuser的时候为系统最高峰，但此时过后，应该还是每隔20S启动5个用户啊？但你的情况是后面又比较平稳了，这个，我个人认为，是不能确定的说系统的最大负载是120个人吧

把你的压力脚本贴出来。看看问题出在哪里

哦,按道理那就不应该是120个是它能容纳的最大用户数,我好多都不懂~

"执行的时候,发现login事务出错很多,基本就是它在出错"

发现Login事务的错误很多的时候，有没有手动去登陆应用检查？

你没有对用户名密码参数化呀。

有队列

kuangquanshui 发表于 2009-6-8 11:51:47

而且你的程序支持部支持同一用户同时登陆多个要是不能报错就是对的了
