Support the ability to tweak application pool performance
We're using WCF and currently we're hard-limited to 12 concurrent requests by the following entry in aspnet.config beneath system.web:
<applicationPool maxConcurrentRequestsPerCPU="12" maxConcurrentThreadsPerCPU="0" requestQueueLimit="5000"/>
It would be extremely useful from a performance perspective to be able to modify this value. I believe ASP.NET 4.0 has this set to a large value, so maybe the problem goes away once you deploy .NET 4.0 in Azure!
