I am looking for information on some of the limits (hard-coded or theoretical) for IIS7 and NLB for website hosting. I have looked around but haven't found anything concrete yet.
On a basic, single server IIS7 setup (Server 2008 x64), is there a limit on how many websites you can host on a single server? Or a theoretical limit on concurrent web requests? I'm not talking about memory limits or resource utilization, I simply mean is IIS7 either hard-coded or limited config-wise to only support a maximum number of websites? 1,000? 10,000? More?
Also, does adding a second server via Microsoft's NLB into the mix reduce any of these theoretical limits?
I will be looking into capacity planning and resource limits later, but for right now I was just trying to find any documentation on what the theoretical limits are of IIS7 itself.
Update: Just saw this blog post with some info on IIS6. If anyone knows if these limits and/or server tweaks still exist for 2008/IIS7, please let me know.
