Monitoring and Tuning Your Server

Tuning Tips

Here are some general tips for maintaining or improving performance.

This may seem obvious, but sometimes people do forget: Make sure debugging for ASP is turned off.
Set Expires for all images and for HTML wherever possible. Proxy servers and browsers will make fewer calls to the Web server as a result.
Remove Microsoft® Visual Basic® objects from ASP Session state if they are Apartment threaded (not Java or most C++ objects, though).
Cache output from ASP if possible; if not, cache inputs to ASP if possible.
If you have a large installation with many Web sites, each attached to a different IP port, your server may create too many backlog monitor threads (the system creates a thread for every 64 Web sites). The workaround for this is to disable the backlog monitor. To disable the backlog monitor, set the following registry key to 1:
HKEY_LOCAL_MACHINE
\System
\CurrentControlSet
\Services
\Inetinfo
\Parameters
\DisableBacklogMonitor
Then restart the FTP and Web services.
Caution Do not use a registry editor to edit the registry directly unless you have no alternative. The registry editors bypass the standard safeguards provided by administrative tools. These safeguards prevent you from entering conflicting settings or settings that are likely to degrade performance or damage your system. Editing the registry directly can have serious, unexpected consequences that can prevent the system from starting and require that you reinstall Windows 2000. To configure or customize Windows 2000, use the programs in Control Panel or Microsoft Management Console (MMC) whenever possible.
