Verify Max Worker Threads Setting

This rule checks the max worker threads server option for potentially incorrect settings. Setting the max worker threads option to a small value may prevent enough threads from servicing incoming client requests in a timely manner and could lead to "thread starvation". However, setting the option to a large value can waste address space, because each active thread consumes 512 KB on 32-bit servers and up to 4 MB on 64-bit servers.

Best Practices Recommendations

Set the max worker threads option to 0. This enables [!INCLUDEssNoVersion] to automatically determine the correct number of active worker threads based on user requests.
