Trusted cache will prevent ColdFusion (5 or MX) from checking the disk for
the file timestamp.
This can have a medium to large-ish performance impact. Huge if your
templates are mounted across the network on a file server.
You can switch this setting on/off without restarting the server, so you can
update a template, flip the switch off, request that page to clear the
cache, and then flip the switch on again. All without restarting. This is
by design.
If you have a large number of pages that you are updating, a restart would
probably be better, or (as Jon Block mentioned) a regression script which
hits every page in your app (using cfhttp).
Macromedia recommends that all performance sensitive sites turn trusted
cache on.

Only if your site has very rare changes.
With trusted cache off, a new change will have a minor delay the first time
it
is invoked while it compiles, and from then on, it will load just as well as
if
TC was turned on.
I was searching for the Link which discusses this extensively, but am
running
against a deadline, and don't have the time to look it up.

| On a production server with frequent changes, it is best that you turn off
| trusted cache and leave it off.

| | Does disabling and then reenabling the Trusted Cache option in CF 5
clear
the
| template cache? If not, how can I make CF refresh the entire cache? Does
it
| require a restart?
