# The Server Settings Page

The Administrator Server Settings page contains several configuration options you can set or enable to manage the ColdFusion server. Many of these options can significantly affect server performance. Use the following table to find out about options on the Server Settings Administrator page.

Server Settings Options
Option | Description
--- | ---
Limit simultaneous requests | Use this value to limit the number of simultaneous requests for the ColdFusion server. Once ColdFusion reaches this limit, requests are queued up and handled in the order received.
Timeout requests | Set a value to limit the amount of time ColdFusion waits before terminating a request.
Restart unresponsive server | This option allows you to restart the ColdFusion Server service (daemon) in the event some ColdFusion component does not respond within the specified amount of time.
Enforce strict attribute validation | Enables strict attribute validation rules. ColdFusion tag attributes that are not relevant to the execution of a tag will not be allowed. When disabled, irrelevant attributes may be passed to CFML tags without effect. Strict attribute validation improves template execution time and can help prevent many CFML coding errors.
Suppress whitespace by default | When checked, the engine will compress runs of spaces, tabs, and carriage return/linefeeds into a single space. This can significantly compact the output of a CFML template. Developers can locally override this setting for a template (for example, to emit preformatted data) by using the CFPROCESSINGDIRECTIVE tag.
Fast Date/Time parsing | (Solaris only) When checked, ColdFusion uses a simpler, faster Date/Time parsing routine when evaluating expressions. Enabling this option improves performance, but may affect backward compatibility. This does not affect the ParseDateTime function.
Missing Template Handler | Lets you specify a default template to execute any time the ColdFusion Application Server cannot find a requested template.
Site-wide Error Handler | Lets you specify a template to execute any time the ColdFusion Application Server encounters errors while processing a request.

When changing values on this page, be sure to stop and restart ColdFusion for these options to take affect. For more information on stopping and starting ColdFusion, see "Starting and Stopping ColdFusion"
