As I just edited, same goes for IP addresses (as everything else); since you post process country codes you do not track the cumulative totals for country results; you only process the last entry (which is most likely only 1).

                                        $updatecache["country_||_$coucode"] = array($existingcache["country_||_$coucode"]['count'], $item['count'], $existingcache["country_||_$coucode"]['cmisc']);

country_||_US will be processed hundreds of times, but since you don't increment the results, only the last record processed is every recorded.
