time delays

In some sites, every manipulation in requests, cause a long time delays to response why is this happening? And also burp suit stops functioning until that website gives a response!

Thanks for your message. Can you email us some more details so we can take a closer look? What changes are you making to the request when you see a delay? If you don't edit the request but just resend it, do you see a delay? Which version of Burp are you using, can you please also send us the details from Help -> Diagnostics, please?
