title: how TCP can be tuned for high-performance one-way transmission?
body: <p>my (network) client sends 50 to 100 KB data packets every 200ms to my server. there're up to 300 clients. Server sends nothing to client. Server (dedicated) and clients are in LAN. How can I tune TCP configuration for better performance? Server on Windows Server 2003 or 2008, clients on Windows 2000 and up.</p>
  
  <p>e.g. TCP window size. Does changing this parameter help? anything else? any special socket options?</p>
  
  <p>[EDIT]: actually in different modes packets can be up to 5MB</p>
