I have a dot net web application. There is one page where we enter data & submit the form.We upload the attachment before submitting the form.The submit action is taking long time almost minute for files with attachment of 650KB. The code behind is C#. We use third party API(Ektron).Its a CMS tool.
Please let me know , in what all ways i can analyse the bottle neck for the issue.Please provide open source Tool & the browser addons.. other than Page speed & Yslow .
