I believe what you are seeing is that %cache is per-child, so it has
to compute it *once* for each child, not once for the server overall.
Also, I'd red-flag your assignment inside to the cache var as
well as the outside. The whole point of the do { } block is to mention
the cache just once. If you need an intermediate place to hold it,
declare it:
return $cache{$key} ||= do {
my $result;
...
.. complex code ..
$result = $something;
..
$result;
};
