I am having a problem with a VB.net application. Whenever I deploy a new version of the website to the servers they seem to lock up/slow down terribly for about an hour or so. Eventually they sort themselves out and return to normal. This has only happened very recently and only with certain websites running from one IIS.
I'm not sure whether this helps but in order to deploy I am deleting everything except the web.config and then copying the new web folder over the top. Should we be restarting IIS before doing this? I am reluctant to do so as we have many websites running from IIS and this would then bring them all down.
Has anyone else seen a problem of this type?
Thanks in advance,
