我的Web应用程序的池性能问题 [英] My web application's pool performance issue

问题描述

大家好，

我有一个Web应用程序，刚进入任务管理器.我的Web应用程序的池在内存中使用了345,000kb的空间.当我检查默认的应用程序池内存使用率时，它表明我的Web应用程序池使用率不到一半.大约是145,000kb.这是平常的吗?我应该担心吗?看起来好多了.我会忘记一些打开的连接吗?或缓冲池内存的查询?如果有人在这个问题上帮助我，我会很高兴.

除此之外，在这种情况下我是否可以改善性能?感谢所有人.

Hello guys,

I have a web application and I have just bumped into in the task manager. My web application''s pool is using somewhere 345,000kb in the memory. When i check the default application pool memory usage it is showing my web application pool usage''s less than half. It is somewhee 145,000kb. Is this something usual? Should i be worried? It looks a lot tome. Am i forgetting some connections open? or a query buffering the pool memory? I will be glad if someone help me in this issue.

In addition to this, is there a way that I can improve the performance in this situation? Thanks to all.

===UPDATE===
