We have a record maintenance page on a web app that we are developing that sits for an age before submitting the form once the 'Save' button has been pressed BUT that only happens under a very specific set of circumstances. We have deployed the site to a couple of our test servers (both of which are running Windows Server 2003 Web Edition SP2 & IIS6), when we access the site on Server A through Chrome (43.0) the submission is very slow but if we use FireFox then it acts as expected and it always acts as expected, irrespective of the browser, on Server B. We have a number of record maintenance forms and this is the only which that exhibits this behaviour, although it is the most complicated form we have.
I can't post the actual code, but we have a RadAjaxManager covering all fields on the form, which we use for field change checking and field validation, numerous control types including four RadAsyncUpload controls and a RadNotification. If I remove the RadAjaxManager, obviously we lose all the AJAX functionality but the Save works as expected.
Unfortunately the Server A is remote and it is not possible to debug on there to try and determine and watch point it if stalling.
Any help/pointers would be appreciated.
Many thanks

I would suggest you to revise the help topic below and test the provided approaches for optimizing the Ajax performance:

and verify if this helps.
