Try pre-loading your counters with 0s and just using UPDATE. I bet it's faster than INSERT ON DUPLICATE UPDATE. Assuming you have reasonable hardware 30k/min (500/s) seems pretty poor. But I guess it depends on how many counters there are and how many concurrent connections are trying to write at once.
