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
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.
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"

from the cfhelp
CFPROCESSINGDIRECTIVE
Suppresses extraneous white space, and other output, produced by the CFML within the tag's scope.
Syntax
<CFPROCESSINGDIRECTIVE
SUPPRESSwhitespace="Yes" or "No">
... any CFML tags here ...
</CFPROCESSINGDIRECTIVE>
SUPPRESSwhitespace
Required. Boolean indicating whether to suppress the white space and other output generated by the CFML tags within the CFPROCESSINGDIRECTIVE block.
Usage
If a CFPROCESSINGDIRECTIVE tag's scope includes another CFPROCESSINGDIRECTIVE tag, then the inner tag's settings override the enclosing tag's settings within the body of the inner tag, where they differ. If the enclosing tag specifies settings that the inner tag does not, those settings remain in effect within the inner tag's scope.
CFPROCESSINGDIRECTIVE settings do not apply to templates included via CFINCLUDE, CFMODULE, custom tag invocation, etc.
Example
This example shows the use of a nested <CFPROCESSINGDIRECTIVE> tag. The outer <CFPROCESSINGDIRECTIVE> tag suppresses unnecessary whitespace during computation of a large table while the inner <CFPROCESSINGDIRECTIVE> tag honors all whitespace to output the preformatted table.
<CFPROCESSINGDIRECTIVE SUPPRESSwhitespace="Yes">
... any CFML tags here ...
<CFPROCESSINGDIRECTIVE SUPPRESSwhitespace="No">
