file upload too slow in IE9 and IE10

file upload too slow in IE9 and IE10

i have a view in MVC that uploads the file to the server and displays data
after reading the uploaded excel or mvc file. Here is the form element
@using (Html.BeginForm("UploadFile", "UploadWizard", FormMethod.Post, new
{ @id = "UploadFileForm", enctype = "multipart/form-data" }))
it is simple upload, it works in all browsers but in IE9 and IE10 it
uploads the of even 1kb in more than a minute. i tried two work around ,
running ie in compatibility mode and adding a registry key, both works. We
can not tell this to the user. There should be something that we could do.
