Last week I posted about a problem I'm having with bad response times from IIS. David Wang(Msft) asked me to post an IISState dump from the IIS server. This message is just to repost that dump in the hopes that someone can help interpret it for me so I can figure out why our application is performing badly. For reference please see the message from 7/20 titled "major IIS performance problems..." The log is enclosed here as well. Can anyone help?
