以上[上传之后]的测试,均指上传之后,第一次访问非静态页面的时候的速度.test.html没有缓存.都是从server抓的.
奇怪的是,只有在每次上传之后,服务器响应才会变得特别慢.连续上传的话,同理第二次就会很慢.
如果另开一个窗口,A窗口上传之后,B窗口一直打开的页面进行跳转,也会很慢!!
感觉就像服务器中断了和client的连接一样..但是就算重新打开浏览器打开页面也没这么慢啊...

不知道大家有没有遇到过类似的问题.还请帮忙指点一二.感恩

dev.spec.
vs2013
IIS8.0
as.net mvc5

需要更多信息还请帮忙说明.谢谢

没人啊..看来要研究一下asp.net生命周期了..

update, 如果只是单纯上传文件.就不会出现"上传之后,再连接server很卡的"的现象. 应该是和数据库处理有关系.. 后台是npoi parse excel 写到datatable之后 ,使用oracle bulkcopy writetoserver的... 初步猜测是和IIS设定有关系...因为第二次请求很晚才到对应controller.到达controller之后的一些列动作都很正常...
