  • Re: IIS express requests take 4 times longer to execute

    IIS Express was built as a developer focused server and the default configuration is setup for maximum debuggability.  There are several configuration changes you can make to dramatically improve performance (but will lower debuggability).  Probably one of the more significant changes you can make is to disable the Failed Request Tracing logging; which is on by default for all requests.  Probably we'll write a blog post soon on configuring IIS Express for faster performance. 

    We would love to use the kernel mode caching, but since we are trying to support XP (and all the other OS's), we could not use that API set for caching; once we're able to drop XP support, we should be able to make use of that API.
