title: Web server capacity planning: more cores versus more memory
body: <p>We have an ASP.NET project (40 or so Web forms, 50 tables, pretty standard IO stuff with care taken to minimize when possible) that will soon need to be deployed. There will be about 100 concurrent users on the system, but only about 20 at any one time will be pounding on it it. We'll be deploying it on Windows Server 2008, 32-bit initially.</p>
  
  <p>When considering production server spec which should we worry more about, getting more cores and less memory (4 cores and 4mb, for example) or more memory and less cores (2 cores and 8mb)? </p>
  
  <p>Would bumping up to Windows Server 64-bit help with memory utilization? </p>
