There may be very simple scripts which are used just once a week or month,

create and don't stay loaded in memory and consume resources for no reason.
If it's only used once a week it won't stay loaded in memory, it'll get
swapped out if there are other tasks that need the memoryi or bits of
the filesystem to cache. Reading it back from swap will be no slower
than CGI.
Reading from cache skips the parsing and require/use resolution steps.
The savings from compiling Dancer into the intermediate form alone
should be worthwhile.
$ time 'perl -e print "x"'
x
real 0m0.001s
user 0m0.000s
sys 0m0.002s
$ time perl -e 'use Dancer;print "x"'
x
real 0m0.535s
user 0m0.110s
sys 0m0.012s
Half a second of page load latency is quite noticeable.
