hellow,

i want to optimize my perl script.

in my script i have one hash of hashes
%hash{$path}= {  Date => $date,
                Size => $size };

[download]

now i want to delete files($path) which size > sizelimit.

solution 1)
-traverse the hash
-compare the size with sizelimit
-Delete the file

solution 2)
-get the array of keys by sorting the hash accorting to size.
-put one condition and break the loop.
e.g 
my @sort = sort {$hash{$a}->{"Size"} cmp $hash{$b}->{"Size"}} keys %ha
+sh;
for each $file (@path) {
  if ($hash{$file}->{"Size"} > $sizelimit) {
     delete $file
  } else {
     break;
  }
}

so which one is best optimizaion(both in memory & speed)??
