Thank you for the replies... This is what ended up fixing the issue and speeding the script up greatly; seconds instead of minutes. I was coverting the unix seconds into a five minute interval for graphing by overwriting the $seconds variable, using it and then adding the interval to it. Instead, I needed to retain the original value, so I needed to use a second variable for the five minute interval. $fivemin = (int($seconds/300))*300;

   foreach $cmd ('WBU', 'RTT') {
        my ( $time, $interval, $n_elements, @data ) = split(/,/, $Clie
+nt{$client}{$cmd});
        my $seconds = &UnixDate("$time","%s");
        foreach (@data) {
                if ($cmd eq 'RTT') {
                        $interval = 60;  ### interval not set correctl
+y in dataset
                        $value    = sprintf("%0.2f", ($_/1000));
                }
                else {
                        $interval = 30;  ### interval not set correctl
+y in dataset
                        $value    = sprintf("%0.2f", (($_*8)/1000)); #
+ Convert to bits then / by 1000 for graphing
                }
                $fivemin = (int($seconds/300))*300;
                $Counter{$fivemin}++;
                $Tot{$fivemin}+=$value;
                $Max{$fivemin}=$value if ($value>$Max{$fivemin});
                $Min{$fivemin}=$value if (($value<$Min{$fivemin})or(!$
+Min{$fivemin}));
                $seconds+=$interval;
        }
