Caching

The Caching Settings page of the Administrator contains configuration options that
you can set or enable to cache templates, queries, and data sources
significantly affect server performance. Use the following table to learn more about
the options:
Option
Template cache
size: [n] kilobytes
Trusted cache
Limit cached
database
connection inactive
time to [n] minutes
Limit the maximum
number of cached
queries on the
server to [n] queries
Description
Enable this option to limit the memory reserved for template
caching. For best performance, set the value to the total
number of kilobytes of all your active ColdFusion pages.
Enable this option if you want ColdFusion Server to use cached
templates without checking whether they changed. For
templates that are not updated frequently, using this option
minimizes file system overhead.
Enable this option by entering a value to limit the time that
ColdFusion Server allows a cached database connection to
remain inactive before disconnecting. Enter 0 if inactive
connections should be maintained as long as ColdFusion
Server is executing. If the option to maintain database
connections is not enabled in the Edit Data Source page for an
individual data source, the option is ignored. For more
information, see "Adding Data Sources for ColdFusion" on
page 115.
Enable this option by entering a value to limit the maximum
number of cached queries that the server maintains. Cached
queries allow retrieval of result sets from memory rather than
through a database transaction. Because queries reside in
memory, and query result set sizes differ, you must provide a
limit for the number of cached queries.
