Hi i have asp.net website, which i am making plan for hosting at Windows Server 2003. Here i would like to know that how many concurrent request IIS6.0 can server?
Actually in my website the number of registration at the time of deployment is around eight thousand and the growth rate is about 100%.
Is there any standard formula by which i can calculate the number of simultaneous request IIS 6.0 can server because it can help me to calculate the performance of website.
Performance isn't a function of only IIS. It has to do with what type of hardware you are running on, what your web application is actually doing and your internet connectivity. Your best bet is to look in to benchmarking tools and try to extrapolate from there, but no, there is no standard formula, since there are so many different variables that affect performance so greatly.
I'd suggest that you use a load testing tool to check the number of concurrent requests vs. response time and find a figure that you're happy with. You should also make sure that your application can work in a web-farm environment if you need to add more physical servers down the track.
