Another option- Partially live. Use the excellent Cache::Cache to cache your output from HTML::Template, and then feed that to your users. Something like:

my $cache=Cache::FileCache->new(); #options here. . . 

my $cache_key=$id; #Cache key that uniquely identifies this page

my $object=$cache->get($cache_key);
my $output;
if( not defined $object){
   # The page isn't in the cache, or it's expired.
   # Create your page,  piping it through HTML::Template.
   $cache->set($cache_key,$object,'2 hours');
} else {
   # The page is in the cache.
   $output=$object;
}
print $object;

The cool thing about this is you can delete the page directly from the cache when it's updated, so you can set your expire times pretty long. In this example I'm caching the entire page, but you can (obviously) only cache the very expensive parts of your application, or NOT cache the parts you want to change on each instance.

I like Cache::Cache a LOT, but you really need to benchmark to make sure you're saving time.
