IIS - Determine Application Bottlenecks

I am writing a windows based application that polls a ASP web page
running on IIS at a set interval with a small amount of data (1KB). The
IIS server responds with a similar amount of data.

I am trying to determine the maximum number of concurrent requests that
the IIS server can handle in terms of both server performance and
network bandwidth. Using the Server Performance Advisor tool it seems
processor bottleneck will not be an issue, but I would like to determine
at what point network bandwidth will become a bottleneck for this
application and whether I can be confident that 10,000+ concurrent
requests to the server for example will not saturate the available
bandwidth of the server.

Can anyone suggest a process/tool to help determine the network
requirements of this application running on IIS?


Thanks.

Re: IIS - Determine Application Bottlenecks

If you only want to check the bandwidth, and you know how much data that
will be sent to/from the server, and at what interval, all you need to do
is calculate. You have all the necessary information.

Re: IIS - Determine Application Bottlenecks

I'm not sure I have as I need to allow for ethernet overhead etc to get
a true measure of bandwidth utilisation. As far as I understand I have
to add 60bytes for each packet and 500 bytes for each tcp connection to
the server. I think maybe Network Monitor can give me this information
but I'm not familiar with this tool yet. I will try netmon, but if
anyone else has any suggestions I would be glad to hear them.

Thanks.
