Without touching the server at all, my IIS 7 suddenly got terribly slow. No matter if I request a static content, a php script via FastCGI or a ASP.NET page, it sometimes takes more than 30 seconds for the server to send the response (even for a 1k static file). The resources are not utilized at all (~1% CPU, enough main memory free). The failed request trace from IIS shows for all those slow responses for every step 0ms processing time, but a total processing time of a few thousand milliseconds. It's also not a networking issue (Apache on the same server runs smooth and the same latency applies for local requests). Anyone has an idea what else to test/check? Have you seen such behavior as well?
