I am developing an upgrade to a corporate website. The website is not intended for public use but just as a tool for internal consultants and analysts. The website is primarily used an audit tool so a large amount of data is added, analysed and then exported into excel sheets, reports and presentations.
In the past, this website has been plagued by slow refreshing and browsing speeds. Therefore, to counter that, I would like to establish some benchmarks and standards for speeds for loading pages, refreshing lists, navigation from one page to another. The standards should ideally be global and should be used by major websites just like Experts Exchange.
Also, we are anticipating a large number of data to be added in coming years, so I would like to know the best ways to perform load and performance tests. Can anyone assist me to achieve the above?
